In my opinion, this game is a complete waste of time. It's just another low-budget indie fps with very little content. There is no single player campaign. It's just a couple of multiplayer maps with zombie bots and no objectives. There is also no manual save. If you die, you must restart. The graphics in the first map are faded and washed out with muddy textures and no brightness/gamma option. The first map also has some strangely harsh lens flares that cause the entire screen to glitch when you stand in one of them. The zombies in the second map bull rush you and attach to you like magnets. The entire game menu is also in Spanish with no option for English. There is also no way to remap the controls and Steam-VR pops up when you start. Don't waste your time with this one. Just play Zombie Army 4 instead.
