What is your favorite alien-slayer game/series?

[Herobrine]

My favorite alien killer game I've played is the Halo series. Then again it's the only one i've played, but that's not my point.

Kid Icarus: Uprising
Aurum are aliens and it's fun to mow em down.
Halo owns too!

Mario & Luigi Partners in time

Halo is pretty damn fun, but Metroid trumps it and almost everything else in everyway...except multiplayer. Maybe. Other than that, the Half-life series is fantastic and Aliens Colonial Marines looks to be good. I'll have to check it out once it hits the Wii U.

Oh, you silly little Chippy, how dare you name the best RPG for the DS?

Young people and their Halo. This is not by far the best I like but I sure have fond memories of it.

Mother 2/Earthbound. Then Halo.

Half Life and Unreal had some of the coolest aliens to kill.

Metroid for me. I like Half-Life but the checkpoint system needs some work. I always wind up respawning with 3 health and then I'm stuck forever. DX

Also Borderlands had some aliens in it or something.

EDIT: Firefall takes the top spot now that I've had a chance to play it.
