Warhammer 40k Table Top rpg

My friend made a home-brew Warhammer 40k rpg out of the Star Wars rpg. It has been working out real well. I am playing the medic in the group, I'm also crazy for the God-Emperor of man. In are game the nids are attacking and we have to fight them off. It isn't going so well. We where held up in a base when they came in from all sides. After the group killed them off a fucking carnifex came thought the wall. We barely lived. Can't wait for the next game, we have are own chimera now.
