After successfully completing the first mission, our hero is now sent to an abandoned military camp, again overrun with Zombies. With more firepower, ranks and skills to unlock this time you should have no problems...
Hope you enjoy the game!
Edit: Guys, to clarify how the game works. You do not need to pay for anything to play the game. When you die, if you play again from the start you will keep your experience and unlock skills like fast reload or red dot sight etc. Every time you play however, you have to unlock new areas and guns again as part of the core gameplay.
If you want the ability to continue the same game after dying, or purchase any of the super guns to make the game easier, then you can.
This is a game trialing a beta version of a new system. If you like the game, great - if you don't then don't make it about the payment system, it should be irrelevant.
