Battlefield 2
Second part in the Battlefield series. Modern weapons and vehicles are used in the game so you can now drive around in a M1A2 tank and fly around in a F/A-18 Hornet if you feel like it. There are seven classes in the game: assault, snipers, spec ops, engineers, medics, support and anti-tank and it is possible to form groups with other players so you can work as a team more easily. One player can act as the commander and can order all the groups around on the map and also use commander assets like satellites and artillery to find and destroy the enemy. Extra fun game when you find yourself in a good squad with good teamwork.
