Battlefield 2 is actually my first online game that I bought. It is an “old” game, but very popular.
The principle of the game is like how other games of this genre. You have a choice between 2 sides, which are fighting against each other. Each side has a spec ops, support, snipers, medics, engineers, assaults and anti-tanks.
Each infantry class has own weapons. Anti-Tanks have among other things bazooka, snipers – sniper riffle, engineers can repair vehicles, medics can treat and reanimate wounded soldiers.
The highlight of the game is, that you can fight not only with your weapons, but you can flight with different kinds of war-plains and helicopters, drive tanks, autos and boots.
For kills and teamwork you receive score that you can see in online stats. With a time, if you play good, you will receive awards and new weapons.
