You asked do you need to update your instruments with time. That means you already have istruments ? If that is the caso, no, not necessarily. For instance, if your guitar don't sound good enough for you, nothing that distortion pedal can't change...well at least it will shape sound. So it won't be very expensive. On the other hand, if you don't have instruments, that is going to cost a lot. In that case try some sport or stick to the gaming

Static-X - Night Terrors

Mostly soldiers stick to their weaponry, but I don't think it is against the rules to take enemy gun. But try not to lose your's though :D

Static-X - Cannibal

Yep. In some show when I was kiddo and I was in movie once. My face in full screen. And I appeared in another scene in same movie.

Night Shift - Missing

Soil - Halo

Randomly chose one of the Cannibal Corpse lyrics and then make it all come true on his hide

Metallica - Creeping Death
