On the other hand the online game is a lot of fun. I actually play about ten hours a day. A lot of guys start squads and have little wars with other squads. It gets reall intense in multi-player. Sadly, in the multy-player game, people will actually use the glitches to their advantage and ruin the game.
People also use trainers and cheat.
I use a trainer too sometimes. You can see where a guy is hiding in a building, becuase of the bad graphics. You can walk through trees. The single player is very boring. The AI are really slow.
