From Eurogamer: “2013’s Aliens: Colonial Marines is one of the most memorable gaming disappointments we’ve ever seen. After witnessing a gorgeous, atmospheric engine showcase back in 2011, fans of the series were hungrily awaiting a true sequel to the iconic 1986 film. But then, in February 2013, Aliens Colonial Marines came out and the horror of its truth became reality. Gearbox’s first-person shooter was an infestation worthy of being nuked from orbit. The AI was broken, the gunplay was unreliable, and the “perfect organism” – the Aliens themselves – couldn’t even run at the player properly.”
