What's more pleasant than playing a Marine Marshall hunting xenos and baddies throughout the entire system ?!!
Unreal series (especially Unreal 2 : the awakening). (especially quake 4), for the same reasons. This games mixes both horror and action, and that's what I love the most. X-com itself lol, Love those challenging games. Half-Life series (and especially Opposing Force) thanks to the HECU. Aliens vs Predator series thanks to the USCM and Weyland Yutani's armed forces. This game is too epic, really, too epic.
Warhammer 40 000 Dawn of War series because of the Imperial Guard/Space Marines/Sisters of Battle.
Just to give you an idea, here are the games I love and already own : I don't care if it's set nowadays or in the future. I know that's not original nor hard to find, but there's so many of them, I can't chose anymore. I'm looking for an epic game in which humans kick some alien/monster asses.
