Essential improvements

Skip Intro Videos

Set the value of seta g_showintromovie in kexengine.cfg to 0 (see configuration file(s) location)

Gigaquad's Enhanced log texts mod

Matches the text to the spoken audio.
Updated to work with the Sept 2018 source port.


Improves music playback. Users of Windows 8 & later may want to see MIDI mapper workarounds first.
The default Windows MIDI instruments library sounds rather low quality and out of place in many parts of the game, visit this Steam guide to learn how to improve it.

Enable reloading and switching ammo with a single keyboard key

Few people know that System Shock has (and always had) a shortcut for both reloading and switching alternate ammo types (Alt+← Backspace and Ctrl+← Backspace). Unfortunately these keyboard shortcuts are less than convenient for modern standards. Luckily they can be changed in Enhanced Edition.

With the Kex Engine sourceport version, you can change these bindings via the in-game control settings section. For the wrapper edition, use the config file edits below.

Edit controls.cfg (2015 wrapper version)[citation needed]

Add the following lines, preferably under the "custom profile" section:

    bind r	 	    cmd.ammotype default 0
    bind shift+r	    cmd.ammotype default 0
    bind tab	 	    cmd.ammotype default 1
    bind {{key|shift|tab}} 	    cmd.ammotype default 1
Requires R (stand) to be rebound for use by reloading.
Additional binding that may be worth looking at and changing are Alt+' (throw grenade), Ctrl+' (next grenade), Alt+: (use patch), Ctrl+: (next patch) and Ctrl+A (automap).

Issues fixed

System Shock won't launch

Fixed in an update.
Turn off MSI afterburner[7]
Run the game in Windows 95 compatibility mode[8]

Game crashes with "ERROR!" after intro

Move the game installation path to somewhere that is shorter than 64 characters.[9]

Final boss fills the screen too fast

Enable V-sync[10]

Reactor code is no longer randomized

Replace archive.dat[11]

Download the archive.dat file and replace the one found in \res\data. The tool reactor-rng can also be used to patch a game that is already in progress.

Note: This fix can cause issues with the automap MFD on the second level. The display can become off-center and significantly zoomed out, preventing the player from using the mini-map.[12]

Lag spike whenever the mouse is moved

Replace bundled SDL2.dll[citation needed]

The SDL version bundled with the game contains a bug which causes lag spikes with high polling mice, this can be fixed by replacing the bundled dll with a updated one from SDL's website.

Blurry/choppy screen when looking around

Change renderer to Vulkan

Edit the config file and set seta r_rhirenderfamily to vulkan instead.

VR support

3D modes State Notes
User created game profile, see vorpx forum profile introduction.

Other information


Technical specs Supported Notes
Added in source port update.
Utilizes SDL 2.0 for output.
Software renderer
Edit shock.ini and set SoftRenderer to on.
Executable 32-bit 64-bit Notes


The 6 September 2018 source port introduced official mod support.


The very first full fan made singleplayer campaign for the original System Shock in over 24 years!

Cortex Reaver Challenge

A challenge room that pit the player up against Cortex Reavers using a Laser Rapier; kill as many as you can before you die, there is no restoration chamber.

High-res objects

This is version 3, which has been updated to work with the Source Port Update.
A version of this mod compatible with the game before the Source Port Update can be found here. Download only "hi-res3DSS.rar", ignoring "v2" - version 2 only adds adding parameters, useless if you don't want to mod the game.

Operating system (OS) 7
Processor (CPU) 1 GHz
