Heretic II is a singleplayer and multiplayer action shooter game developed by Raven Software using id Software's id Tech 2 engine and published by Activision. Unlike all other games in the Heretic series, which were shooters in the first-person perspective, it is a third-person shooter with slightly more of a focus on platforming elements through granting the player new acrobatic moves. As its name implies, it is a direct sequel to the original Heretic (though it takes place in the same universe as the other games, Hexen: Beyond Heretic, the entry that followed Heretic, is an indirect sequel).

The game was first released for Windows on November 24, 1998. A Linux version followed on December 6, 1999, then an Amiga version in 2000 and a Mac OS Classic version on November 22, 2002.

Because of rights issues between id Software, who published all prior Heretic games (with the exception of Hexen II's mission pack, Portal of Praevus, which was also Activision-published), and Raven Software, Heretic II is unavailable for digital purchase. However, it has received patches, both official and unofficial. Raven's Enhancement Packs, culminating with Enhancement Pack v1.06 in May 1999, would add a new defensive spell, a female player model, and various other improvements. On December 29, 2012, community member WhiteMagicRaven would release the unofficial Enhancement Pack v1.07 which, among other additions, allows for widescreen resolution support.


Source DRM Notes Keys OS
Disc check (requires the CD/DVD in the drive to play)
To install on 64-bit systems, go in the setup folder and run setup.exe.
Mac OS
Owners of the Loki Software Linux port of the game should consider using the installer from LIfLG, in case the game is run on a newer system. It is currently in beta.


A demo is available, but the single-player portion cannot initially be played due to a date delimiter that does not allow it to run after November 1, 1998;[1] there is a patch that fixes this.

Essential improvements


Enhancement Pack v1.06 is the latest official patch of the game, with changes to gameplay and several fixes. However, the framerate is capped at 30 FPS with this patch.
Enhancement Pack v1.07 is a community patch that includes Enhancement Pack v1.06, restores the framerate to 60 FPS, includes support for widescreen resolutions and other changes.

Widescreen resolution

Use H2Resolution.exe[2]
  1. Install Enhancement Pack v1.07 into <path-to-game>.
  2. Open H2Resolution.exe.
  3. Enter the desired resolution into the Width and Height fields and press OK.
  4. On the Heretic2.exe, set DPI scaling to application (right-click -> Properties -> Compatibility -> dpi settings -> Override high DPI scaling).
  5. Launch the game.
  6. Either open the console with ~ and in set vid_mode 3, or select the 640 x 480 resolution in the Video Settings menu.


Lower vertical FOV at wider aspect ratios (Vert-). Increase FOV to compensate, see Field of view (FOV).
HUD, FMVs and menus are stretched at aspect ratios wider than 4:3 by default. Use the Enhancement Pack to fix the stretched HUD.

Field of view (FOV)

Change FOV manually[2]
  1. Install Enhancement Pack v1.07 into <path-to-game>.
  2. Launch the game.
  3. Open the console with ~.
  4. Type in fov X and enter, with X being the desired FOV.

Alternatively, with Enhancement Pack v1.07 still installed:

  1. Go to the configuration file(s) location.
  2. Open config.cfg with a text editor.
  3. Find set fov and enter the chosen FOV.


To maintain identical vertical FOV to the 4:3 FOV at 16:9 resolutions, use 106. At 21:9 resolutions, use 121, for 32:9 use 139, and for 48:9 use 152).

Frame rate

Unlock higher framerates
  1. Install Enhancement Pack v1.07 into <path-to-game>.
  2. Launch the game.
  3. Open the console with ~ and type in set cl_maxfps X, replacing X with the desired framerate limit value.
  4. Type in set cl_predict 0, this disables multiplayer prediction/smoothing code that breaks at high framerate values (resulting with increasingly broken movement/animations). This has adverse effect in online play, as everything will be updated only along the 10 Hz server tickrate with no smoothing.


Engine is hard-capped at 1000 FPS, it will lose sync with its own listen server above 500 FPS. The game is intended to be played at 30 FPS with minimal changes occurring at 60 FPS.
There are aspects of gameplay that will be negatively affected by increasing the framerate limit, such as:
  • Directly scaling with framerate possibility of getting stuck at 90 degree edges like some stairs or steep (unwalkable) slopes, resulting in player either getting stuck or receiving random fall damage.
  • Player melee damage seems to somewhat increase along with framerate (unconfirmed).
  • Swim up/down speed scales directly with framerate.
  • Damage received from environmental hazards like fire/steam scales directly with framerate up to being nearly instantaneous death.
  • Some moving elements of the levels won't move correctly (with little to no risk of soft-locking).

Issues fixed

Erroneous visibility blockers at widescreen aspect ratios

Disable precalculated vis leafs
  1. Launch the game.
  2. Open the console with ~.
  3. Type set r_novis 1 to disable precalculated level visibility areas.


This will negatively affect performance (to a negligible degree on modern hardware).
On some levels where level geometry continues above skybox of prior parts (such as Katlit'k Canyon), this will result with further parts of the map being visible above in the sky.
