It's a simple Smash TV rip off with repetitive level design, horrible dialogue, and an unfortunate lack of multiplayer.
Smash TV features fun and diverse characters, entertaining boss battles, and many other features that Cash, Guns, Chaos severely lacks.
Cash, Guns, Chaos also seems cheap. Once you hit the money limit that you're supposed to obtain, enemies will still go after you. If you die... even if you have the required amount of money, you're forced to start the level over. That can be a giant frustration because it happens more frequently then you expect.
The weapons are fun at least. Once you get some of the special weapons, you actually have fun killing people. Sadly, you don't get those weapons for long. Killing enemies with a giant rocket launcher is a bit more entertaining than the simple, boring default weapon.
Level design is nothing but a square throughout the whole game. It's like the developers didn't even try. They change the scenery every once in a while, but the level remains just... a box. There are no obstacles, there's nothing special about these levels.
Enemies are boring. None of them have totally awesome unique powers. Enemies will shoot at you, or try to hit you. They're all relatively the same, (except some take longer to die) they just look different.
The game's dialogue is not as funny as it thinks it is. Most of the lines in the game are poor attempts to make a 12 year old laugh. It has an immature sense of humor, that has been seen in so many other games, but done better. I can laugh at immature humor, it just has to be done right.
Overall, Cash Guns Chaos is occasionally fun, but mostly a repetitive Smash TV rip off that doesn't reach Smash TV quality. It's uninspired, repetitive, and not worth your money.
