Good game and similar to dead trigger 2. Problem is the guns and gadgets. In dead trigger 2. You can cheaply buy med kits guns, and explosives. This game has the same things but its gold only to buy them. Not very many high powered guns. I have the top guns but cant finish levels because they arent powerful enough. I recommend going with dead trigger 2 instead.
