5.1 Scoring

(i) Damage: Players get points for the amount of damage they inflict on monsters.

(ii) Kills: Players also get bonus points for making a kill which is 10% of the total health of the monster. The Boss Brain gives +5000 points on death.

(iii) Extreme Death Kill Bonuses: On top of the Kill points, players also get bonus points for making an 'extreme death' kill which takes the monsters health down to more than negative it's initial health. This bonus gives 10% of the total health of the monster. Extreme deaths are when certain monsters explode into gibs. This rewards players creating more carnage with powerful weapons.

(iv) Secrets: Finding a secret gives +250 points.

(v) Map Objectives: In multiplayer, bonus points are given for players who reach certain objectives in the level first. These include: getting to a keycard or skullkey first (+250 points), opening a door with a keycard or skullkey first (+250 points), reaching the level exit first (+250 points), reaching a secret level exit first (+500 points). In SP, bonus points are still given for reaching these objectives, since in some wad levels: keys, colored doors and secret level exits can be optional depending on secrets found etc... Additional support has also been given for 'any key' (+250), 'All 3 keys' (+750), and 'All 6 Keys' (+1500) doors.

(vi) Map Items: Collecting a map item gives +5 points. Any item counted as a map item in Doom, is one that can always be picked up, and goes towards the Item Count percentages at intermission screens. Items like blue health flasks, armor helmet bonuses, radiation suits, artifact powerups, automap pickups, beserk packs, infrared goggles etc... Not armor suits, health pickups, ammo or weapons.

(vii) Par Bonus: The bonus/penalty to be added depending on how well the player beat the map's ScoreDoom par time. Its based on a percentage of the total points scored so far for the level.

(viii) Chain Bonuses: If a player can kill 4 monsters in a very short time, they will get a small bonus of +5 points or more (depending on the monster's starting health), which accumulates up to a +5 or more point bonus, for every other monster killed after that, just as quickly. If the player can keep the rampage going, they will eventually get a full Chain Bonus of +5 or more points per monster. (NOTE: Any extreme death bonus will also be added to the chain bonus score for the killed monster, which essentially doubles the extreme death bonus during chain bonuses. This rewards players creating more carnage with powerful weapons.)

(ix) Co-op Death: There is a -500pt penalty for death in co-op games which come from monsters, environmental hazards or suicide. Death from other players has no penality. Points can never be less than 0. This was added in mind to stop players taking advantage of deliberate suicides, as well as a general penalty. This score does not get applied in SP, since the level is reset on death.

(x) Monster Infighting Deaths and Monster Suicides: Since monster deaths due to infighting and suicides are ultimately player assisted, there is a small bonus for these deaths too. In SP, it is equal to the kill bonus of the monster (10% of the original health). In Co-op, the current level points leader (*not the total wad score leader on the HUD!*) scores a bonus equal to the creature's kill bonus, whereas every other player scores a fraction of this depending on the ratio of their score for the level to the level points leader score. No player can get less than 1pt, and only the current level points leader will (should!) get the full bonus. The rationale behind this was that the level points leader probably deserves the bigger bonuses, and it also forces the other players to attack more to get in front.

(xi) Barrels: Barrels give +5 points when destroyed.

(xii) Artifacts: Clever use of ScoreDoom artifacts can help contribute to very large scores.

Each player has a 'Wad/Epi Score' for the whole wad(s) being played and 'Level Score' for each map being played.

5.2 ScoreDoom Par Time & Par Bonus in Detail

ScoreDoom uses a fairly simple formula based on the amount of monsters, secrets & items in a level to dynamically determine a reasonable par time for the players to complete a level AND kill all the monsters. For the official Doom & Doom 2 levels, it works out to be very roughly at least around 3x the standard par times, sometimes a lot higher. Higher skill levels (more monsters) will give higher par times. For lower skill levels the par time should never be less than the standard default par time.

The Par Bonus is a little more complicated, but it is also calculated using a fairly simple formula based on the elapsed time for the level, the ScoreDoom par time and the player's points for the level. The Par Bonus will be seen to go down and this may be confusing, but the Par Bonus is actually the points which would be added should the player complete the level RIGHT NOW. It is set up so that players will lose all their points for a level should they take from 10 to 20 minutes after the par time is over to complete the level. This is meant to stop players taking advantage of arch-viles and pain elementals to rack up infinite scores, as well as making them kill/score faster within the par time.

The formula to compute the par bonus is as follows: (level par time - time taken)*(points scored)/(level par time * 5)

Players will lose all their par bonus points if they fail to complete the level within the par time. When the time taken goes over the par time, a warning is issued to the players, and a new but similar formula is used, based on the the level par time, which more quickly penalizes the players. Players may lose all their points for the level, if they fail to complete the level within 10->20 minutes after the par time is over. (See below for more details).

A quick example may also be instructive of how the par bonus works. Suppose a player racks up a level score of 1000 points and then completes the level at 1/4 par time, 1/2 par time, 3/4 par time and finally at full par time. Another player does the same thing but finishes with 2000 points, the following table shows the respective scores the players will get:

% Of The Par Time The Level Was Completed At	Level Score	Par Bonus	Total Points
25%	1000	+150	1150
25%	2000	+300	2300
50%	1000	+75	1075
50%	2000	+150	2150
75%	1000	+25	1025
75%	2000	+50	2050
100%	1000	+0	1000
100%	2000	+0	2000

Players with higher scores thus have more to lose, the longer it takes to complete the level.

Maps with ScoreDoom par times up to 5 minutes, will allow the players 10 minutes to complete the level with a score more than 0 points after the SD partime is over. Maps with par times between 10 and 20 minutes will give the players an extra amount equal to the par time to complete the level. Maps with par times over 20 minutes will only give the players an extra 20 minutes to complete the map, over the SD par time of the level. So when the players go over the SD par time, the par bonus can become a serious par penalty.

5.3 Hi Score System

*NOTE: in version 1.8+, Hi Score messages will be shown on the upper RHS of the screen in SP and are persistent, as long as the Hi Scores are beaten.
Hi Scores are saved in the zdoom-yourusername.ini file, under [HiScores] so make sure you back up that file or section.

Hi Scores are only saved after a level is completed (i.e. during intermission screens & finale screens).

Hi Scores are determined based on the current wad configuration loaded. So if you play with say '-file icarus.wad' then again with say '-file icarus.wad -icar28a.wad' or with other wads loaded, they will all have their own hi scores. So it is important to be consistent with what wads are loaded and also the wad order (when using a bunch of single level wads together say).

Hi Scores do not apply to multiplayer, so scores will not be saved in co-op.

Hi Scores in Nightmare Mode will not be saved.

When using custom monsters, the distribution of monsters in SP may change with updates to ScoreDoom, which can affect Hi Scores.

A note on Level Hi Scores VS Wad/Epi Hi Scores: Wad/Epi Hi Scores are based on scores added up for a single session of play across one level or more within a wad configuration. Score Doom supports saved games for this also. Level Hi Scores are also recorded per level. It is possible to play a single level and beat it's hi score without changing the Wad/Epi Hi Score, thus the sum of the Level Hi Scores can be greater than the Wad/Epi Hi Score, for a wad configuration in the [HiScores] section. Level Hi Scores are probably better attempted during a session of play (this includes saved games) across several levels or full megawads, since players likely start off with extra weapons at the start of levels.

ScoreDoom HUD in Singleplayer

ScoreDoom HUD in CO-OP Multiplayer


ScoreDoom Intermission HUD in CO-OP Multiplayer


ScoreDoom Finale HUD in both CO-OP Multiplayer & Singleplayer

Artifact	Icon	Description
Speed		Gives the player a boost of speed which lasts roughly 2 minutes. Beware that the player can then outrun their own missiles!
Dark Servant		When pressing the 'use' key (default is enter/return) when this artifact is selected, a large Maulator Demon is summoned to fight alongside the player. The Maulator will also score points for the player who summoned it. The Maulator lasts for roughly 1 minute. Each player may carry a total of 3 of these artifacts. *TIP: Only summon when standing still, or when walking or running at full pace.*
Half Damage		Reduces the damage players take to 1/2 that of normal. Lasts roughly 1 minute.
Quarter Damage		Reduces the damage players take to 1/4 that of normal. Lasts roughly 1 minute.
Quad Damage		Player inflicts 4x their usual damage. Lasts approximately 1 minute.
Regenerate		Player will heal 5 hit points of damage every few seconds until the effect wears off after roughly 1 minute.
Vampirism		Player will heal 1/2 of the damage they deal out, until the effect wears off after roughly 1 minute.
Terrorsphere		Player will frighten or 'turn' monsters so that they run away and attack less. Effect lasts approximately 1 minute.
Time Freezer		Literally stops time, except for the player (and other team members in co-op). Effect lasts for only a few seconds.
Double Damage		Player inflicts 2x their usual damage. Lasts approximately 1 minute.
Precognition		Gives the player the full map for the rest of the level, as well as allowing the player to see where all the items and monsters are within a level via the automap.
UAC Sentry Turret		Players can press the 'Use' key to deploy a turret at a location and it will attack all demons and zombies until it is destroyed, scoring additional points for the player who deployed it. Each player may carry a total of 3 of these. *TIP: Only deploy when standing still, or when walking or running at full pace.*
UAC Smart Bomb		A top secret weapon deployed by special forces teams to help eradicate the demon hordes. Powered by cold fusion, it creates multiple very high frequency super-sonic shockwaves directed around the player which can destroy almost all living and metallic entities within a close range, up to 1000 hit points, as long as they are in sight. Large structures and some demons are impervious to its effects. It also has a receiver which can detect fellow marine transmitters, which allows the weapon to spare them. Each player may carry a total of 1 of these. Hit Key '8' to bring the weapon up.
Big Backpack		Gives the player 100 bullets, 25 shells, 25 rockets and 150 plasma cells. You may also find a UAC Sentry Turret or UAC Smart Bomb inside.
Maulator Demon		Summoned when using the Dark Servant artifact, this demon ally is a ferocious, fast moving death machine which can 'level the playing field' and score the summoner a lot of points. It sticks around for about a minute or so.

*NOTE: As of ScoreDoom version 1.9, sdmonsters1.5.wad & sd-artifacts.wad are now contained in the 'skins' sub directory and loaded automatically.*

Scoredoom supports 3rd party monsters created for zdoom & gzdoom. Any Doom wad you play, with the SDmonsters wad loaded, will cause Scoredoom to selectively add extra monsters (it actually replaces a certain percentage of the default monsters) to the wad being played. It is possible to face up to 170 different monster types (including The Icon of Sin) when playing with sdmonsters1.5.wad
This is meant to add variety to the wad being (re)-played. The custom monsters chosen and ScoreDoom's 'intelligent' replacement code attempts to keep the original 'feel' of Doom intact. Its best just to play a game and see.

There are 2 types of replacement algorithm, one which is 'static' for single player, another which is 'dynamic' (the default zdoom one) for multiplayer. In single player (SP) whenever a wad is replayed *on the same skill level*, the distribution of custom monsters and artifacts never changes. This is deliberate since hi scores are more meaningful with the same enemies being fought each time :P

In multiplayer (MP) the distribution of custom monsters and artifacts change every time a level or wad is replayed, since hi scores are not kept in multiplayer. Singleplayer can be made to behave the same way by setting the following console variable in your zdoom-<yourusername>.ini as follows:

sp_random_custom_monsters=true

Beware that hi scores will be still be saved. You can delete level & wad hi scores though in your zdoom-<yourusername>.ini, just by deleting the relevant lines.
For instance the lines:

|doom2.wad|A|M14|MAP01=2986
|doom2.wad|A|M14=6961

represents Doom II being played with the sd-artifacts.wad & sdmonsters1.5.wad, the first line being map 1's hi score and line 2 being the wad combination's hi score.

The best way to play with truly random monsters per play in SP, is to start a 1 player multiplayer game with +dmflags & +dmflags2 (see Multiplayer Tips section) set to how you want them. You can still save MP games too. (Though IIRC, zdoom's beginning of level autosave feature may not be enabled for MP.)

A few extra points to be aware of when using sdmonsters1.5.wad:
1. The main boss levels in Doom & Doom II etc.. will not have their Boss's replaced, though these Boss monsters can, and will be replaced when they appear in other levels.
2. Player's maximum ammo for clips, shells, rockets & cells is increased, as well as the ammo per pickup for these ammo. This is to help deal with the tougher and more challenging custom monsters. Health pickups are increased likewise too.
3. Using SDmonsters wad with certain zdoom/gzdoom specific wads (like Demon Eclipse), which contain the same custom monsters (actors) will cause a conflict error. SDmonsters wad needs to have all its actors renamed so it will be more compatible. Until then, these wads will have to be played w.o. extra custom monsters.
4. The seeding for random monsters in SP is dependent on the same data that the hi score system uses. So it is imperative to make sure that the exact same wads & wad order is preserved if you want to keep everything the same.

 Back to top

The weapons are there for deathmatch purposes. Unfortunately Doom doesn't distinguish between co-op
and DM weapon spawning, so you'll either have to use those or manually turn off multiplayer weapons.
Go into the menu, hit "OPTIONS" and go to "gameplay options". You should see a big list of stuff to
check off. Take a moment to check off everything you want (and get rid of anything you don't want),
then once you're done write down the two numbers that show up. Remember which is under "dmflags" and
which is under "dmflags2"! Then quit ZDoom and start setting up your game.
When you start up the game, add "+dmflags  +dmflags2 " to the command line.
For instance, if you want default values for everything except you don't want those extra weapons,
you add "+dmflags 1048576" (omitting dmflags2 since you don't need to specify anything for it).
When the game starts, you should see the normal, singleplayer weapon placements.

To apply from the command line just start it with +dmflags *dmflagsnumber* and +dmflags2 *yourdmflags2number*

somewhere in there, example:

gzscoredoom.exe -iwad doom2.wad -file impencse.wad -host 2 -warp 25 -skill 3 +dmflags *dmflagsnumber* +dmflags2 *dmflags2number*
