You aim and fire with your mouse, manage your amo carefully, and pick up weapons and power-ups that drop between waves to stay alive just little longer. If you want to play13 Days in Hell free without downloading a thing, this is exactly the kind of game that loads instantly and pulls you in for "just one more run."

Tips & Tricks
- Save your shotgun ammo for clustered groups, not single zombies coming straight at you.

- The zombies in later waves move faster at night, so position yourself near the center to give yourself room to dodge.
