All the digital distribution versions are pre-patched with NewDark.
OS X and Linux versions use Wine.
A faithful higher resolution icon for Windows can be downloaded from the Files section.

Essential improvements[edit]


Essential patcher which integrates the NewDark patch and fixes various issues.
Latest versions automatically disable the intro video for you (if you wish to re-enable it for whatever reason, add always_play_intro to the cam.cfg or cam_ext files).
SS2Tool requires Vista or later due to included Rsync, however NewDark runs on 2000/XP or later. One can patch it on a Vista machine then transfer it to an older machine. Digital versions already include NewDark and compatibility fixes for modern systems however the tool is still necessary for proper mod support.

Recommended mods[edit]

Modding guide available on the PCGamingWiki blog.
Alternate modding guide with updated links and mod info, from the System Shock 2 forums.
Mod list
  • Shock Community Patch - Fixes various bugs dealing with texture inconsistencies and general map issues. There's also a yet to be included prison event fix available here. Note that it also rebalances some weapons; a revert mod is available here.
  • Olfred's fixed objects - Fixes many small imperfections of SS2 objects: missing polys, z-fighting, incorrect texturing etc. Note that SCP already integrates the fixed objects and SHTUP includes modified versions with higher res textures, but Olfred's pack is usually the most up to date; load with higher priority than SCP but lower than SHTUP.
  • Portraits Fix - Fixes inconsistencies with the character portraits from e-mail and message logs. Recommended to be used with SCP but is not required.
  • SHTUP - Improves the texture quality of the level objects and scenery. Recommend using with earth dynamic/static newsky and Vurt's Water. Yet to be included military logos are also available as well as a fix for a (at the moment) broken texture, install the texture by placing it in SHTUP's \obj\txt16 folder. You can also fix a duplicated texture on explosive barrels by deleting the file brl_exp.bin in the obj folder, allowing the Olfred's or SCP version to load.
  • 400 - Improves the texture quality of the levels' terrain.
  • Rebirth - Increases the poly count and textures of in game NPCs. Recommend using it with the High Res Protocol Droids and Eldron's Midwife as Nurse Bloome. Also checkout Cutscene 2 Rebirth, which was a project to update the in game cutscenes with the rebirth models. Unfortunately only one Cutscene 2 Rebirth cutscene was ever made, but it's quality is excellent.
  • Scary Monsters AI Enhancement and Enemy Health Randomizer - Can give some variation to the games archaic AI.
  • Denoised Cutscenes - These cutscenes have been upscaled to 640x480 and had the static noise from the original outdated encoding removed. To make compatible with Cutscene 2 Rebirth, either set to lower priority or merge it into this mod, overwriting cs2.avi.
  • Tacticool Weapon Replacements and RocketMan Alternative Weapons Pack - Improves the appearance of the in game weapons, both world models and in hand models. Tacticool focuses on standard and energy weapons while RocketMan focuses on heavy and exotic, however both packs include their own versions of the wrench; pick the version you like the most. Unfortunately neither of them include replacements for the EMP Rifle or Laser Rapier. You could use R&R&R's EMP Rifle to give the EMP Rifle a skin however. Recommend using with JMP Jack's Hires Weapons with player hands to give two handed weapons a proper second hand.
  • Kyu's Weapon FX - Adds enhanced graphical effects to weapons, such as smoke/heat distortion leaving the barrel after firing. Also has optional weapon rebalancing and MiniHUD.
  • Vurt's Organics / Goo - Improves the appearance of various organics in game. Recommend using in conjunction with Vurt's Flora Overhaul and Kaucukovnik's alternate wormpiles and wormbeakers. Note that SHTUP already includes biomatter, however Vurt's can be used as an alternative.
  • Vaxquis Vintage Song Remake - Adds higher quality music to the game.
  • DeepFriedBeer's Sound Upgrade and LarkSS' Small Sound Modification Pack - Improves the in game sound effects, particularly weapons. Note that the Small Sound Mod includes an elevator theme, which the original game lacked. If you do not like this, delete the elevator.wav file inside snd/amb.
  • Rickenbacker Automaps - Adds real automaps to the Rickenbacker level. A minor alteration to some map sections can be found here.
  • Quest Note Notifiers - Adds notification sounds for when a new quest is added or it's goal changes, similar to System Shock's successor BioShock.
  • SS2 HUD Logs - Make emails display a portrait of the sender, again like BioShock.
  • Replicator to Inventory - Items purchased at replicators are automatically added to your inventory.
  • GamePig Unleashed - Restores some missing minigames.
  • Repairman and Stasis Trap - Makes the repair skill and Stasis Field Generator actually useful.


  • Alt weapon sounds - An alternative/expansion to DeepFriedBeer's Sound Upgrade that improves the weapons effects furthor (you can merge and overwrite DeepFriedBeer's original files if used as an expansion). Note that this mod contains a Duke Nukem voice clip for the weapon break sound, which can break immersion for some players. To fix this delete the file gunbrek1.wav (or if being used as an expansion simply don't copy).
  • Silversharp's Weapon Sounds - Yet another weapon sounds pack.
  • Vurt's Hi-Res Space Textures - SHTUP already includes a space texture, but this is a nice alternative.
  • Necro Water - Alternative to Vurt's Water.
  • Hi-Resolution Player Models - Rebirth includes player models, but here's nice alternatives.
  • ImpyNickers RebirthSkins - Makes the Rebirth Hybrids look more vanilla (scary). Requires basic Rebirth to be loaded first.

OS X version[edit]

Modding the Wineskin version can be done by firstly installing the Windows version in a virtual machine, patching it and installing all desired modifications and then replacing the System Shock 2 installation within the Wineskin version with the custom version. If you are using the Steam version it may be necessary to deactivate Steam's "Keep up to date" function for this to work.

Issues fixed[edit]

Random crashing[edit]

Small game window or black screen[edit]

Edit cam_ext.cfg to disable multisampling[citation needed]
  1. Go to the installation folder.
  2. Open cam_ext.cfg using Notepad.
  3. Comment out and change multisampletype 8 to ;multisampletype 8
Enable SS2Tool Safe Mode[citation needed]
  1. Download and run the SS2Tool installer.
  2. At the Choose Components installation step, enable Safe Mode.
  3. Click Install and finish installing.

UI too small on high screen resolutions[edit]

Edit cam_ext.cfg to enable ui scaling[citation needed]
  1. Open cam_ext.cfg in Notepad or any other text editor.
  2. Uncomment the line ;d3d_disp_scaled_2d_overlay 64 by removing the semicolon.


If this does not fix the issue, you may try scaling the UI to arbitrary resolutions by re-commenting out the above line (add back in the semicolon), uncommenting the line ;d3d_disp_scaled_2d_overlay 640 480 and adjusting the 640 and the 480 to your desired resolution. However, this may cause the ui to become blurry/pixelated, so try the initial fix first.

Poor performance on Mac wineskin version[edit]

Enable X11[9]

Find the System Shock and right-click on it. Click Show Contents and run In the Screen Options, you should see a checkbox that says Use Mac Driver instead of X11. Uncheck that box and that should fix the problem. If box is already unchecked then check it instead.

Can't dive in Mac or Linux version[edit]

Place this dml file in the SS2 folder[10]
