Essential improvements[edit]

Gigaquad's Enhanced log texts mod[edit]

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


Improves music playback. Windows 10 users may want to see MIDI mapper workarounds First.

High-res objects[edit]

Note that this mod is currently incompatible with the Sept 2018 source port release.[6]
Improves texture quality whilst not suffering from the slow downs the DOS version had.
  • Download only "hi-res3DSS.rar", ignoring "v2" - version 2 only adds adding parameters, useless if you don't want to mod the game.

Input settings[edit]

Enable reloading and switching ammo with a single keyboard key[edit]

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.

Edit controls.cfg[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 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).

Adding mouse-wheel support[edit]

The following section is redundant since the 6 September 2018 Source port update; the game now natively supports binding actions to mousewheel up and down
Use AutoHotkey[citation needed]

Copy the following into a text editor and name it MOUSEWHEEL.AHK:

#ifWinActive, ahk_class SDL_app
#SingleInstance Ignore

SendEvent +{q Down}
Sleep 200
SendEvent +{q Up}

SendEvent {q Down}
Sleep 200
SendEvent {q Up}

; Middle mouse button: Grenade, the "e" key below counters ModePicking allowing you to retain aim after prepping the grenade
SendEvent, !{'}
SendEvent, !{'}
SendEvent, {e}

; 4th mouse button = Inventory left
XButton1::Send, !{[}

; 5th mouse button = Inventory right
XButton2::Send, !{]}

WheelLeft::Send, !{[}
WheelRight::Send, !{]}

Assuming you already have the AutoHotkey suite installed, compile the script into an application. Now open a text editor again and copy the following into it, save it as a .bat file:

TITLE System Shock: Enhanced Edition

Place both the batch file and the compiled app into your System Shock: Enhanced Edition installation folder and use the batch script to launch the game.

If you modified the key bindings you may have to modify the script as well to be compatible with your new layout (! is for Alt, ^ is for Ctrl, + is for Shift).
Making the Steam launcher and GOG Galaxy open the scripts instead of the executable alone may require compiling the batch script into an exe, renaming sshock.exe (don't forget to edit the batch to reference the new name prior to compiling) and name the newly compiled batch in it's place.

Audio settings[edit]

Select MIDI Device[edit]

System Shock: Enhanced Edition has MIDI playback hard-coded to Device 0.
Hex edit executable to change MIDI device[citation needed]
  1. Open DOSBox and run MIXER /LISTMIDI to get a list of your MIDI device IDs.
  2. Open sshock.exe in a hex editor such as HxD
  3. Search for the first instance of hex values 6A 00 6A 00 6A 00 6A 00. In HxD this should appear at Offset 000019C0.
  4. Edit the last digit to that of your desired MIDI device ID. Using Device 5 as an example, this would be: 6A 00 6A 00 6A 00 6A 05.

Issues fixed[edit]

System Shock won't launch[edit]

Turn off MSI afterburner[8]
Run the game in Windows 95 compatibility mode[9]

Game crashes with "ERROR!" after intro[edit]

Move the game installation path to somewhere that is shorter than 64 characters.[10]

Final boss fills the screen too fast[edit]

Enable V-sync[11]

Reactor code is no longer randomized[edit]

Replace archive.dat[13]

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]
