@137ben To kill the Trex, just stay in the middle area for as long as you can. I'm not sure if you have to be a certain level, but he he sped up and tried to bite me pretty early on in the level.
It's a good game. If anyone thinks it's too much reading, they don't have to play it. I'll admit that some bits were a bit weird, but the ending made me feel just a little bit better about life. So my question is, why rate something like that down?
ax, yeah, the zombie lvl takes 200 or so kills. in the room before that, wait for the synthesized lifeform room. they have stinky beans, tons easier, don't use the bean rifle on any other enemies though...
