its a great game but wow does the enemy get too hard to fast and guns are expensive as fck I played this on first release and after only a few stages the enemy become unbeatable unless you spend big money you need to upgrade your weapons to move forward after every single mission just be warned need deep pockets or a sugar daddy/mammy

Outstanding game, been playing it almost as long as it's been out. Lots of different characters, skills, and weapons to choose from for a lot of variety in gameplay. And even once you've unlocked ''everything'' (there's always another big update coming), there are plenty of ways to challenge yourself. I highly recommend it, very fun way to waste a couple of hours of freetime.

TThe game is awesome and love the way the music and graphics are put out on the game but it's a pain in the as with the limited number of guns and equipment that easily breaks although the rank or tier of the weapon is high its frustrating. But all in all love the game
