I was just realizing earlier when I tested it, it sucked, but its only on the first stage.
I need more room for the tyranids to move around, and some bigger tunnels so the fex can get inside the base and slaughter everyone once he jumps out of his hole. Ill give the ending away, the base blows up and everyone dies, no thunderhawk no harpy comming to save them they all DIE. And no I am not mad right now, it may seem like that but I ain't

*Edit* Ill make a new thread or post thingy once I have a bit more on it, won't be long, should get it good by this week, Monday---Friday. Hammers also being stupid, making move by brushes and objects while holding alt key when I am not holding it :C
