At first, its really hard to learn whats going on, and what to do, and all the type in commands, but when you figure it out (if you ever figure it out) you play for a while and level up and its some what fun for a while. Then you get to a certain level, and the only way to level up and higher is to pay, which considering the bad graphics and stuff its really not worth it. The game looks like a gameboy game. Everyone who has too much free time and nothing better to do who decide to pay and continue to level up dominate the people who don't pay. They get like sniper rifles, grenade launchers, stuff to make them invisible and make them move really fast, much better armor ( so good beginners cant kill them) and stuff like that. The best you can get not paying is an "electric paintball gun." Its definitely not worth the time (or the money).
Dont download it, even if you did pay its not worth it.
