The game itself, when it works, is very nice. You can choose to fly a fighter/bomber kinda plane, drive a tank, lay landmines, or shoot with a variety of weapons. The graphics are topnotch, with the explosions being especially noteworthy.
What really sets this game back are the bugs, flaws and glitches. Aside from the gameplay issues that need to be sorted out (and there are a lot of them), Incognito has had major problems since launchday with it's servers. To this day, problems with logging on and getting kicked off servers persist. The online ranking system is a complete mess (a messed-up ranking system that effectively limits an already limited choice of servers), and there are any number of glitches in the game that allow players to cheat in a variety of ways.
In short, it's a good game, but be prepared for some real headaches in playing what is still a game in development.
