I've made one about Quake 3, well, my clan. And been pondering making one about Bioshock. Especially before it gets released, heh.
Anyway here's the link to the Q3 song if anyone wants to hear. I do cuss a lil, so....caution?
BTW, the Bioshock song would be TEN FOLD better. I made that like 2 years ago. It'd have a dope chorus and everything.
