EDIT: Could have been an excellent game
Single-player is boring, but easy. But, multiplayer could have been so much better. Plagued with connection problems and a poorly executed persistent online world hurt the game seriously.
The game is good. Building your mech is easy and fun. Actually getting your mech online to fight is really really exciting. But, nowadays, finding games can be hard, and takes forever. Nobody is playing anymore, sadly. The problems with the game weren't fixed fast enough, so I guess people left.
I'm sad, this could have been an amazing game, but poor support let this game die.
