The Mustard Virus has gone global and wiped out humanity. You're all that remains, well - you and the endless waves of infected. How long can you last? Will your base be strong enough to stop the horde?
The infected are relentless. They're attracted to light, sound, and most of all - players. Sunlight no longer has any effect on them, and they'll stop at nothing to get to you!

This is the FAST ZOMBIES variant.
It is considerably more difficult. Good luck.
