Zombie Outbreak - action game

Zombie Outbreak is a free online flash game of the category action games.

Zombie Outbreak beta

This is the first flash game i've ever made. So it may run slow on some machines and may have some bugs.
Zombies will keep coming on to you until you're dead. Keep running from them while shooting. And don't forget to get health packs which will spawn every now and then. Stronger weapons will spawn in time. Minigun is the strongest and will spawn last. Minigun and Chainsaw have fixed ammo count so don't expect more ammo.
As I said this is my first game so there is only one screen in the game. You cannot leave the intersection.
Feedback always welcome. I hope that you enjoy it. Have fun!
WASD or Cursors to move SHIFT: Sprint LMB: Shoot E: Last weapon 1: Pistol 2: Dual Pistol 3: Shotgun 4: Rifle 5: Minigun 6: Chainsaw F: Turns flashlight on/off. P: Pause game

A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
