i killed some weird bird in halo 2, forgot what level but they where flying around and i shot one with a sniper adn it rained blood XD. Its the level where you fight those hunters then the pelican drops some ammo and you jump on this floaty thing that takes you across to this tower thing.......and then you get in this submarine elevator thing, yeah i know i have the best description in the world no need to thank me.
Oh god. The Halo 1 sniper rifle is horrid. I don't know how it compares in strength, but it is so hard to actually HIT someone when you're shooting at them. It's ridiculous. Not to mention the giant cloud that bursts from the sniper when it's fired.
