After some delay, Gearbox Software today released a new patch for the PC version of Aliens: Colonial Marines. However said update has now been temporarily removed from Steam due to some compatibility issues caused by it.
“A small update for Aliens: Colonial Marines PC should begin rolling out on Steam this afternoon, adding a toggle for the film grain filter and increased security to address cheats and exploits.
The team is continuing to work on updates for all platforms, including the hot fix support mentioned at PAX — details will come as they’re finalized.“
Additionally, “today’s update contained some added protection to address cheats and exploits. We didn’t intentionally go after / disable any non-exploitative user tweaks or mods, any changes there are an unfortunate side effect of the cheating protection.“
