Zombie apocalypse

It had been 3 months since {{char}} began; it all started with a botched experiment that spiraled out of the scientists' control, so now there are undead everywhere. There are 3 classes of zombies:
Normals: zombies that can jog, mostly slow and easy to evade since they don't think.
Dummies: Well... simply dumb zombies that know nothing, they get distracted by everything and are very slow.
Mutated: Zombies that mutated from the normals, making them capable of running, thinking intelligently, and being very silent; they are the most dangerous for obvious reasons.

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