CstDoom3-BFG v1.0 released


About

CstDoom3-BFG is a mod for Doom 3 BFG Edition. It has many gameplay options and fixes a considerable amount of bugs. See the next sections for an overview.

Features for Doom 3, RoE, and LM

Below is a description of the main features for Doom 3, Resurrection of Evil (RoE), and Lost Mission (LM). Notice that everything is optional and can be configured using the menus

Show Access Codes: If enabled, when you interact with a GUI that requires an access code (like the keypad of a locker), a window magically appears on the HUD showing the code you need to enter. This is quite handy if you are tired of searching for codes in emails and audio logs.

Access Codes

Double Barrel Shotgun and Grabber in Doom 3: The Double Barrel Shotgun and the Grabber from RoE can be used in the Doom 3 campaign (there is an option for each one). If enabled, these weapons can be found in Mars City Underground, Hell, and Delta 5. Important: Changing these options take effect only when a new campaign is started.

Chainsaw in RoE and in LM: The Chainsaw from Doom 3 can be used in the RoE campaign and in the LM campaign (there is an option for each one). If enabled, this weapon is easily found in the beginning of the game (Erebus 1 in RoE; Enpro 1 in LM). Important: Changing these options take effect only when a new campaign is started.

Handheld Flashlight: The classic handheld flashlight from the original Doom 3 is available.

Headlamp: Yet another light option. The new player headlamp is similar to the Armor Mounted Flashlight, but it is view centered and doesn’t need batteries.

EnviroSuit in Erebus 5: In the original RoE, the final section of Erebus 5 was toxic, so you had to wear the EnviroSuit and had to keep it supplied by collecting EnviroTanks. In the BFG Edition, this EnviroSuit quest has been removed. If the “RoE Erebus 5 EnviroSuit” option is enabled, the EnviroSuit quest will be present as in the original RoE. Important: When Erebus 5 is entered, this option is evaluated only once, so you must make your choice before reaching this map.

Phasing Effects in Delta X: In the original RoE, the Delta X map (Delta Labs – Unknown) had creepy hell phasing effects. Red lights, smoke, and skeletons would periodically appear and disappear along with a FOV effect and phasing sounds. In the BFG Edition, the whole phasing scheme has been removed. If the “RoE Delta X Phasing” option is enabled, the phasing effects will be present as in the original RoE. Important: When Delta X is entered, this option is evaluated only once, so you must make your choice before reaching this map.

Run, Crouch, Zoom Indicators on HUD: If enabled, an indicator is displayed on the HUD while run/crouch/zoom is active (there is an option for each one). This is particularly useful if you configure these controls as toggles. The indicators can be seen in the image below (lower left). Run is red with “>”, crouch is yellow with “-“, and zoom is blue with “+”.

HUD Indicators

Extended FOV Range: The field of view (FOV) can be adjusted from 80 to 115 in steps of 1 using the menus, and the FOV value is properly stored.

Allow Skip Cinematics: If enabled, cinematics can be skipped by pressing the Esc key.

Shotgun Spread Reduction: If enabled, the Shotgun spread is reduced by half in singleplayer. This makes the Shotgun noticeably more effective.

Grenades Toggle: If enabled, pressing the Grenades key toggles between Grenades and the previous weapon.

Old Health Station: If enabled, the health supply of Health Stations will be the same as in the original Doom 3 (less health).

Old Ammo: If enabled, the ammo pickups will have the same amount of ammo as in the original Doom 3 (less ammo). There is an option for each campaign (Doom 3, RoE, and LM).

Old Player Speed: If enabled, the player speed will be the same as in the original Doom 3 (slower movement).

Additional Key Layers: The keyboard and mouse keys have additional layers to which controls can be assigned. If you use this feature wisely, all relevant controls will be “right below your fingers”, so you will never need to look at the keyboard during gameplay.

Demigod: This is something between god mode and the actual gameplay. When demigod is on, your health and armor levels decrease as usual when taking damage, but your health never drops below 1 (so you never die). Rumors say that you must enter cstDemigod at the console to enable it.

Run Freely: The “Always Run” and “Toggle Run” functionalities are available in singleplayer, and stamina drop can be disabled.

Smoke Toggles: The muzzle smoke of any weapon and the fly smoke of any of their projectiles can be switched off.

Damage Feedback Toggles: Any of the player’s damage feedback mechanisms (double vision, tunnel vision, view angle kicks, etc.) can be disabled.

And More… Explore the menus and see what else you can find.

Features for Doom Classic

A number of features are also available for Doom Classic (Doom and Doom II). Notice that you must use the menus of Doom 3 to configure them.

Re-assignable controls: All controls of Doom Classic, including the automap controls, can be reassigned. The new layer system is also available.

Automap Options: You can adjust the zoom step, zoom speed, and pan speed to be used with the corresponding automap controls, and you can decide if “follow mode” should be enabled automatically when the automap is opened.

Run Options: The “Always Run”, “Toggle Run”, and “Run Indicator on HUD” options are also available for Doom Classic. These options are independent of those for Doom 3.

Screen Options: The frequent screen flashing in Doom Classic can result in eye strain for some people, so a number of options have been added to help with this. You can decide if the screen flashing/coloring when picking up items, taking damage, or using power-ups affect the whole screen, only the status bar, or are disabled. Weapon muzzle flashes and the screen effect when exiting teleporters can also be disabled. If needed, a brightness option is available too.

New cheats: Rumors say that new cheats can be enabled by entering cstDcDemigod or cstDcGive at the console while playing Doom or Doom II.

Carmack’s Reverse

The depth-fail method for stencil shadows (aka Carmack’s Reverse) is available in CstDoom3-BFG (the related US patent has already expired; see here). This method is enabled by default, so you don’t need to configure anything to use it. Compared to the unmodified open source engine by id Software (this one), the visuals remain the same, but you can expect better performance when the view is in shadows.

Achievements

The achievement system is enabled in CstDoom3-BFG, but for local use only (it isn’t related to Steam or any other online service). Since the usage is local, the console restriction has been removed (the achievements can be unlocked even if the console has been used).

The state of each achievement (locked or unlocked) and progress information for each one are shown on the Achievements menu. The Reset Achievements button in this menu can be used to reset all achievements to the Locked state (confirmation is requested twice).

Achievements

You should also be aware of the following changes:

  • The “To Be or Not To Be” achievement has been replaced by the new “Out Of The Frying Pan” achievement: You must free, not frag, the scientist in Alpha Labs 4.
  • The “DOOMed Collector” achievement has been changed so that picking up the PDAs available in the maps is enough. Killing NPCs for their PDAs is no longer needed (PDAs from killed NPCs don’t count anymore).
  • The “I Like To Watch” achievement has been changed so that all video discs must be picked up, including both discs with the “ancient civ” video (one in Site 3, the other in Caverns 2).
  • The “Goody Finder” achievement has been changed so that all storage lockers, without exception, must be unlocked. Most are unlocked with a code, but some are triggered when you move through certain areas. In Mars City Underground, one of the lockers is unlocked by saving the scientist being attacked by a zombie (how many of you knew about this?). In Delta 3, one of the lockers becomes accessible by teleporting to Hallway or Storage using the last teleporter.

Bink Videos

The Bink videos from Doom 3 BFG Edition need to be converted to another format to be played by CstDoom3-BFG. This is because CstDoom3-BFG supports Theora videos (in a custom container called TH) instead of Bink. A utility to automate the conversion is included. You’ll also need the RAD Video Tools (for the conversion only). See the installation instructions in the manual for the details.

Bug Fixes

Tons of bugs in the BFG Edition have been fixed, some of which are quite unexpected. Here are a few examples:

  • As you know, many objects have been removed from the BFG Edition, but not as many as you think. A bug was causing several objects to fall though the ground after being spawned. These objects would disappear or become partially buried as a consequence.
  • Some view effects weren’t working correctly. The tunnel vision, for example, was completely broken and would cause the view to become permanently tinted (!!!) after you took any damage.
  • Many in-game GUIs wouldn’t work correctly after the Artifact had been used in RoE.

Besides actual bugs, some bug-like things were also “fixed”. Here are a few examples:

  • The number of decals is now unlimited (as in the original Doom 3). Get ready to see lots of blood splats and bullet holes.
  • The collision of ragdolls against other ragdolls has been re-enabled. Now you can make piles of dead zombies if you want (they’ll no longer “pass through” each other).
  • Weapon lights are now allowed to illuminate other models. This also fixes muzzle flashes not beign visible.

For the complete list of modifications, see the included “changes.txt”.

Additional Notes

  • CstDoom3-BFG works with the Steam version of Doom 3 BFG Edition (tested) and it should also work with the GOG version (untested). It does not work, however, with the original (non-BFG) versions of Doom 3 and RoE (but the standard CstDoom3 does).
  • Windows 8 or above (8.1, 10) is required. Windows 7 isn’t supported.
  • The complete source code is included.
