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

This is a good game, because there is not an immense amount of pressure to spend money. The rewards are quite generous, and there are many side objectives to do.

Very nice game, you can get a lot of items with the in-game currency that you receive a decent amount by just playing the game. Play to enjoy i would say.
