Brazilian, 20 years old, gamer, guitarist and mathematician (hell yeah, I take math classes at college). That's all you need to know.
Stuck in a part where you have to put 3 batteries on a thing that I don't know how to name :/ I've went through the tunnel, killed some headcrabs and stuff but I'm stuck right after. What should I do?
Btw, as far as I played is awesome. Nice mod!
