This custom Serious Sam Classics patch includes a lot of modern enhancements that aren't present in the original code, nor the official Steam patches.

This includes patches for the game (custom SeriousSam.exe), dedicated servers (custom DedicatedServer.exe) and tool applications (custom SeriousEditor.exe and EngineGUI.dll replacement).

1. Download desired version of the patch (TFE1.05_<date>.zip or TSE1.07_<date>.zip for Steam).
2. Navigate to the game folder and extract contents of the ZIP archive into it.
3. Agree to replace existing files (original game files are included with an _OG suffix at the end of the name).

• This project is based on Serious Engine 1 SDK, meaning that it's perfectly compatible with vanilla Serious Sam Classics.

• If you want Steam to start the patched EXE file, backup Steam's SeriousSam.exe and rename SeriousSam_Custom.exe to it.

• If you wish to change player's field of view, it's advised to use sam_fCustomFOV (or sam_fThirdPersonFOV) command instead of plr_fFOV from now on.

  • If you want closer zoom in Cooperative gamemode, you can continue using plr_fFOV but then it's advised to set custom FOV commands to -1.

• If HUD seems too big and overlaps with other elements (especially with sam_bAdjustForAspectRatio on), consider scaling the HUD down using hud_fScaling. The value of 0.75 seems good enough even for 21:9 resolutions.

• If you get an error "Cannot set function patch..." upon game start, make sure that you've installed the executable for the right game version. Otherwise try restarting your PC.

  • If you keep getting the error, create PatcherOutput file (without extension) in the same directory as the executable file to see exactly where it fails. You can see the same output in the SeriousSam_Custom.log file in the root directory afterwards.
