Deus Ex Poster Upscale

SnakeMod

A Deus Ex mod focused on keeping a vanilla game experience by including only mission fixes and quality-of-life improvements. In-progress saves can use this mod!

Improvements

  • Added a new system whereby you can learn codes (and logins) from any source and then are presented with a list of known codes in a new UI window whenever you use a keypad, computer, or ATM that you’ve learned a code for. Selected codes can then be entered automatically (with a simulated typing effect). Learned codes will properly persist through level changes, mission progression, and savegames. Works with existing savegames but will only “know” codes going forward.
  • Added a new version of the Ninja HUD theme (“Darkness”) that’s even darker so as not to blind the player when game brightness is turned up and in a dark area, i.e. most of the game. Also, added a function to reload themes so the new theme can be used in an existing savegame.
  • (Shifter) The Power Recirculator aug will now automatically activate whenever using it would decrease overall power use, and similarly will automatically deactivate whenever it is using up more power than it is conserving.
  • Made it so that an enemy that’s currently stunned or gassed won’t react to getting hit by a TRQ dart.
  • Added a few console commands:
    • AllCodes: works with the new code learning system to allow the player to know all valid codes and logins
    • AllKnownCodes: allows the player to know all knowable codes and logins
    • Cheat: toggles cheat mode for use with key binds and without any convoluted command line arguments or console commands
    • ToggleHud, ToggleGhost, and ToggleInvisible: simplified toggle-able versions of existing cheats for use with key binds
  • Included optional HDTP support. Requires using a different DeusEx.u package.

Fixes

  • (Shifter) In Mission 2, the player won’t be given a bloodthirsty reputation if Anna or the UNATCO troops kill some of the NSF at Castle Clinton.
  • (Shifter) In Mission 2, Ford Schick will always appear at Smuggler’s later if you rescued him.
  • (Shifter) In Mission 4, Paul won’t die if you saved him from the raid and then exit the hotel through the apartment window.
  • (HDTP) In Mission 4, fixed a book that gets destroyed by opening Paul’s closet.
  • (Shifter) In Mission 5, the player’s credits will also be confiscated and taken to the Armory along with the rest of their gear.
  • (Shifter) In Mission 5, placed a new copy of a datacube that falls through the world in the MJ12 command center.
  • (Shifter) In Mission 6, corrected a typo issue that caused the Buddha display case in Maggie Chow’s apartment to not be movable in GOTY versions.
  • (Shifter) In Mission 6, disabled the idle chatter from MJ12 troops hiding in Maggie Chow’s apartment.
  • (Shifter) In Mission 12, made it so the Bob Page hologram didn’t react to certain stimuli such as getting shot (and then start running around the level).
  • In Mission 14, fixed a security computer having a reversed username and password for a login that you could learn. Seems like this was a developer mistake.
  • (Shifter) Fixed a bug where starting a new game while playing an existing game could cause many items to carry over to the new game.

Installation

  1. Decide whether or not you wish to use HDTP, the “high definition texture pack” for Deus Ex that upgrades all of the models in the game. (It’s a pretty decent mod, although the new characters don’t look that good IMHO. But thankfully, you can disable those via a new in-game menu.)
  2. If you do want to use HDTP, then you need to download the version of this mod that includes support for HDTP. You’ll also need to download and install HDTP. Then, rename the DeusEx.u file that comes with HDTP in DeusEx\HDTP\System to some other extension, effectively disabling it.
  3. Backup (rename) your DeusEx.u file in DeusEx\System and then place the copy from this mod’s archive in the same directory.
  4. Run the game and you should see “SnakeMod” version information on the main menu to confirm the mod is active.
  5. If you’re playing with an existing savegame, note that you will need to reload the themes from the Settings > Colors menu (or enter the command ReloadThemes in the console) to use the new HUD theme.

DirectX 10 Renderer HDR Fix

This modest adjustment to the HDR effect of the DirectX 10 renderer improves the playability of HDR by making the below changes. Remember that you need “Classic Lighting” turned off in the renderer settings to enable HDR.

  • The range of luminance adaptation levels is clamped between a high and low limit. Prevents overall too dark or too bright scenes.
  • The speed of the adaptation is vastly reduced; it only takes about a second now instead of ~30 seconds.
  • The adaptation response is slightly less linear, so that both subtle changes in scene lighting have a smaller effect on adaptation, and bold changes have a greater effect.
  • There is a slight preference to the center of the screen when adapting luminance, so that what you’re looking at has a greater effect than what’s in the periphery.
