Here it goes. I spent enough time in the game (Roughly 30 minutes) to make a decent review. The game is not that bad, but it's repetitive. There's a clear lack of content in the game which developpers could've worked on more, by that i mean there is only two type of ennemies for example (Regular mutants and Mutant Dogs) even though some could say some mutants get tougher with time. I managed to complete te first level on the normal and easy difficulty, there is indeed an easily perciptible difference between the two difficulties, i would never picture myself playing the game on the ''Insane'' diffuclty as i'm already haveing loads of difficulties on both normal and easy difficulty. Core gameplay is far from innovative, top-down repetitive shooting with questionnable gun animations. I must admit i enjoy shooting mutant hordes with my M16, it is really enjoyable, but you must do this ALL the time. There goes the levels: Kill, Kill, Kill a horde, Kill mutants in vehicule, press a switch and wait for horde, kill horde, finish level. Indeed there is vehicules but the poor controls makes them less enjoyable than you'd think and the game also suffers of a low variety of vehicules. I took a look at the achievements to realise there isn't that much levels, and some managed to easily finish the game under 50 minutes which is a really poor time for a 9.99$ game. In all honesty it is the kind of game i would enjoy buying at 1.99$ and playing on my tablet or my cellphone. Other than the joy of shooting hordes with your M16, the game is, let's be honest, bad. It could've been more developped content-wise but also gameplay-wise. I had luck to get a two pack for me and my friend at 2.24$ Please don't waste a precious 10$ on this game.
