This map was CANADAs ARMY EH's Idea, but I asked for his permission to post this map, so don't say I stole his idea.

Quarantine V.2
The infection starts in the attic, and quickly spreads through out the small building. The humans are trapped in the building and have no way of getting out the building. Defend yourself in 5 differents place and save your ammo because weapons are rare... Zombies are weak, but watch your back because it's a close quarters map (Similar to Save One Bullet).

Weapons (Never Respawn)
2 Shotguns - 0 Clips
3 SMG’s -1 Clip
3 Magnums - 1 Clip

Equipment
4 Frag Grenades - 60
4 Firebomb Grenades - 90
2 Deployable Covers - Never

There's 3 floors in the building, a basement, and an attic (where Zombies start off).

Teleporter to Basement, 1 Shotgun, 1 SMG, 1 Deployable Cover, and 1 Frag
