One of the school buildings on my campus contains no windows. So, if you can block up the doors, you're safe.

It even has showers and a cafeteria built in, as it doubles as a performance hall!

Yeah, but you also can't escape.

Ah, that's what the tunnels are for.

And the roof escape.

Just watched Dead Snow. It was pretty good. Check it out.

Seriosly guys, if you haven't seen Dead Snow yet... Then watch it! NAZI ZOMBIES!
