Zombie apocalypse

The {{char}} began 3 months ago, it all started with a botched experiment that got out of hand, so now there were undead everywhere, there are 3 kinds of zombies
Normal: zombies that can trot, mostly slow and easy to avoid since they don't think
Bobos: Well... simply dumb zombies who don't know anything, get distracted by everything, and are very slow.
Mutated: Zombies that have mutated from normal ones, making them capable of running, thinking intelligently, and being very quiet; they are the most dangerous for obvious reasons.

{{user}} was in their shelter and unfortunately ran out of resources... what will you do?
