Tweaks / Improvements

  • Added the new map, Metro
  • Added the new Lerk Abyss skin.
  • Removed Exo Railgun target highlighting, as it could introduce severe frame-rate drops in some cases. We may revisit this at a later date, but for now it was worth removing.


  • Fixed that Marines could see consumed Tunnels in the kill feed.
  • Fixed the Retry or Reconnect console commands not being usable when already connected to a server.
  • Fixed that the client would not receive a popup warning them that mods have been disabled when updating to a newer version of the game.
  • Fixed Railguns being unable to deal damage to an alien when the skybox was behind them.
  • Fixed wrong damage numbers showing from corrosive damage. For example, using Bile Bomb on a 90 armor marine would show 146 damage instead of 180.
  • Fixed damage numbers showing too much damage done to Exos upon death.
  • Fixed the killing shot done to an empty Exosuit showing separate damage numbers.
  • Fixed Main Menu background sound effects would continue playing when loading into a server or local mod.
  • Fixed that Drifters could not patrol between more than two points.
  • Fixed warm up mode showing the default Armory model instead of the Advanced Armory.
  • Fixed the Arc Factory research progress would not actually show on the Tech Tree menu.
  • Fixed the typo in the Commander Prototype menu that said “Jetpack, Jetpack”.
  • Fixed a crash when disconnecting from a server.


  • New atmospheric cityscape sound added for Metro (Thanks MasterG!)


  • Metro (new map)
    • Special thank you to the following people and all of our Map and Play Testers:
    • Kash – Project lead, 2d/3d signs, some in-editor work
    • Mephilles – Lots of in editor detailing and bug fixing.
    • pSyk – Performance master, in editor detailing and final lighting.
    • Shrimm – Lots of in editor detailing, Bug fixing and NAMT leading.
    • Loki – Map’s godfather and visionary.
    • Zavaro – Reskinning assets and tweaking trim textures
    • Samoose – Extra textures, loading screens
    • Paul Wolfe – Stalls and holograms
    • Runestorm – A metric ton of new textures, decals and models
    • Vlaad – Many awesome 3d models (lamps, streetlights, the truck, ac units etc)
    • MasterG – City Soundscape.
  • Unearthed (Thanks Kash!)
    • Lighting Tweaks mapwide, unearthed in general should perform better, especially with shadows enabled on high quality lights.
    • Altered collision issues map wide to make for a smoother experience.
    • Fixed stuck spots in Transfer, a lot of stuck spots indeed.
    • Holes fixed in multiple spots throughout the map.
    • Occlusion alterations in Toxic Pool, Transfer, Regulation and Furnace to address performance concerns in those areas.
    • Added a sheet of cover to Toxic Pool.


  • Editor – Fixed that box selection could be a little bit too sensitive, resulting in the mapper sometimes unknowingly selecting a large amount of stuff behind a wall when they only wanted to select the wall.


  • Added “wetmaps” to the game. This allows mappers to specify regions that should appear “wet” or “damp” without having to modify materials to create wet variations of them. Similar to fog volumes, mappers can specify “wetmap volumes” — areas bounded by an arbitrary mesh volume and give it a “wetness” value. Then, the sharp edges can be smoothed over by placing wetmap decals.

Known Issues

  • Reflections do not initialize in the main menu on first launch.
