Orion: Dino Horde is a pretty interesting game. It's a wave-based survival shooter where you fight dinosaurs, with a Halo-inspired art style. They're doing a free week, and it's on sale for 3.74, so there's no reason not to check it out. Also, you can jetpack around shooting a T-Rex with a rocket launcher.

so hows that free hat

Yeah, that was transparent. It's a pretty cool game when it isn't crashing, though, I would actually recommend trying it if you have the patience for such things.

So there is a lot of crashing?

Oh yeah, a ton. They're pretty irritating, because the game would be a really solid recommendation if not for them. As is I'd give it a try anyway during the free week, and then buy it if it strikes your fancy. I will say though, so far they've only been from the escape menu and sometimes on loading, so they don't actually interfere once you get started playing.
