guys... dont pick LOUD THINGS. GOD.
if we choose quiet weaponry then when the guys/girls from the dorm sound the alarm again, the zombies will shuffle away, some will stay, but we wont have nearly as many, allowing us to slip into the mechanics bay, hijack a car, and modify it with parts we took from the shed.
Ex: Barbed wire from the top of the fence, metal plating from other cars, or even some large scrap iron pieces possibly tossed around the shed, spare pieces of wood no doubt found inside of the shed, miniature propane tanks and welding gear, Nail guns, sledehammers, pickaxes, shovels, a ladder, canisters of highly explosive or flammable chemicals, oil drums, fire resistant gloves, iron pipes, etc.
Possabilities are endless :3
After we get these possible things, we can craft a crude machine to escape from the campus, since no doubt some zombies have probably entered our dorm whilest we were away.
