Beaten Halo (Win/PC version) on the easiest level.
As well as the hardest level. v=^____^=v (those are two victory signs, by the way)
Not a bad game at all, although somewhat addictive, due to a well designed combination of often auto-saves ("checkpoints"), and a moderate number of weapons (10 total, I think) and low limits so hoarding isn't too possible: 4 fragmentation grenades and 4 plasma grenades max, relatively low ammo limits, as well as a limit of two weapons on your body at once, with one active at one time. This means players have to either juggle weapons along the ground, or pick carefully what they wish to carry. So it's not really just a "grab every weapon and bash your way through" sorta thing.
And there's a nice amount of sniping, which is always fun. I like long ranged combat. It's safer.
Anyways, yes, back to studying now. Or maybe bed first. We'll see.
