Unreal Survival

Unreal Survival is a mini-game inspired to the zombie mode of call of duty.  

One player must survive endless waves of attacking zombies, earning points from killing or damaging zombies.  

These points can be used to purchase/upgrade weapons or unlock new areas and activate other special objects.  

Zombies become stronger and in higher numbers upon the completion of each round.  

On occasion, zombies will drop power-ups such as Ammo, Nuke, Speed Boost or Medkit upon their death, making the round easier. 

Think you can find out all the secrets and how many rounds can you survive?
