This game is very involved. It needs continuous playing if you want to achieve any sort of "ranking". It has multiple levels, various gameplay, different missions and campaigns. It also has your own Base, which you can upgrade as you advance in rankings. The "squads" and weapons all get stronger as you rank up also. It is true that even though this is a game where you have to "grind" your way up the ladder it is doable. With the help of "gold", in game "currancy", "rubies", and chest's with power-ups, this game will keep you playing once you get involved! All the negative reviews I've seen are from people that have not even a few hours into the game and Steam users that are between level 0 to level 10! Those of us who have been playing this game for a while now know about the errors, crashes and stuff, and we just continue on! Only play if you have the maturity to handle it!
