OpenCAGE is an open source modding toolkit for Alien: Isolation which allows access to a large range of game configurations and content through a simple user friendly interface.

The toolkit is broken down into three main sections: configurations, content, and scripting.

Configuration editors support:

  • AI Behaviour Trees - full access to view and edit all behaviour trees in the game through a flowchart UI.
  • Difficulty Settings - difficulty specific modifiers for character senses and alien configurations.
  • Alien Behaviour Parameters - search radius, vent roam ranges, search time, and director AI settings.
  • NPC & Player Attributes - hostility, attack groups, peek speeds, max health, health regeneration, and more.
  • Locomotion - steering speeds such as cornering weight, acceleration, warping, and more.
  • AI Vision - viewcone parameters, letting you change the view distance and field of view for a character.
  • AI Senses - flamethrower sense, movement sense, flashlight sense, visual sense, touch sense, and more for NPCs.
  • Items and Inventory - maximum items able to be carried, base ammo count, weapon names, and more.
  • Weapon Ammo - fuel consumption, physics impact effects, damage per character type, and accuracy.
  • Movie Playlists - map/sequence specific loadscreen and cutscene movie playlists.
  • Blueprint Recipes - blueprint required item types and amounts as well as number of items produced.
  • Hack Tool Difficulties - hacking speed, pickup range, ease to complete the hacking minigame.
  • Environment Lighting - environment radiosity, deferred lighting, skin shading, and hair shading settings.
  • Graphics Settings - custom FOV, resolutions, LOD, and shadow settings - plus ability to enable hidden options.
  • In-Game Text - any text in the game including Sevastolink logs, mission names, subtitles, and more.
  • Door Codes - any keycode in the game for doors and lockers, with supporting UI text.
  • Material Properties - material-specific settings such as impact effects, physics, and more. [WIP]

Content editors support:

  • In-Game UI - ability to import/export the game's GFX UI files which can be edited by a Flash decompiler.
  • Textures - ability to import/export textures, some formats still in testing (please report issues!).
  • Models - coming soon!
  • Sounds - coming soon!

Scripting editors support:

  • Particles and VFX - particles and other FX can be tweaked.
  • Trigger Volumes - 3D trigger volumes can be positioned and sized to trigger events.
  • Objectives - ability to tweak calls to the game's objective system.
  • Scripted Sequences - ability to tweak animations, positions, etc of scripted sequences.
  • AI Control - control over the AI systems to change behaviours/responses.
  • Mathematic Logic - support for mathematic logic such as addition of integers, floats, and vectors.
  • Collision Volumes - dynamic 3D collision volumes can be edited.

More scripting features will be unlocked and extended as progress continues on the tools.

Hi, I've got a problem with the tool: when I select an option on the menu it opens a window that is bigger than my monitor resolution, and I can't move or edit the size of the window.

Can someone help me with this, please?

Such a great looking game.
The effort they put into capturing the look from the original GOOD ONE really shows.
But kinda busted as far as gameplay.

The levels are confusing, the Alien AI is a chore more then fun.
Unlimited saves may have alleviated same of the awful rubberband AI, but save areas probably makes it worse. Although it DOES feel like a classic obnoxious SEGA game for all that.

The only way I could find to make it fun was just disabling the Alien and me against the Ash robots running around the beautiful scenery.

Amazing Tool, the possibilities... great work there. I was just digging in and tried to export a script from the game, wanted to fiddle with it and change what is happening when, change triggers around, locked doors and rooms that load...sadly, it is not yet implemented, gnaaaah have to be patient... but cheers again to your work!

Implemented in some regard now! Work still continues, but this early release allows for initial editing functionality.

Does your mod allow for modification of the difficulty level in the Survivor Mode maps? It is my understanding that the Alien's difficulty is set to Hard in those levels. I would like to bring it back to Normal difficulty like in the main game. Thank you :)

Yep! Check out the alien behaviour editor for specific parameter configs, or the behaviour trees for more global behaviours.
