As late as 2011, the game didn’t even have a working script. Timegate employees were pretty surprised to find that in four years Gearbox had basically just jammed together a bunch of ill-matching assets. Borderlands had just caught fire though, so Borderlands 2 and Duke Nukem Forever (uh oh) became their primary focus, and they brought in Timegate in 2010 to finish the majority of development.
Sega bought the rights to the Aliens franchise in 2006 and Gearbox was to be the primary developer. Gearbox and Timegate are most often credited as doing the lion’s share of the work, but Demiurge Studios, Nerve Software, and Check Six Games are also credited. One red flag right off the bat is how many developers are listed on the box, not to mention Sega and EA (oh boy) are both listed as publishers, though it’s likely EA was more of a distributor.
