Each map has two opposing armies fighting over a territory.To win the match one team must reduce the other team's "tickets" to zero.
Finally, if the game timer runs out, the team with most tickets wins.
There are seven player classes in Battlefield 2: Spec Ops, Sniper, Assault, Support, Engineer, Medic and Anti-Tank.
Players start at Private and, as they play the game, they earn Private First Class, Sergeant and so on.
Each promotion earns the player a new weapon unlock.
The types of vehicles range from small, fast jeeps to amphibious APC's to Main Battle Tanks to jets and helicopters.
Each faction in the game has its own set of vehicles, though each vehicle in a faction has an analogue in the other factions that performs essentially the same function, with minor statistic adjustments.
Each class has 2 weapons to unlock, each of which replaces the class's primary weapon if chosen in the class selection screen.
Battlefield 2 was the first game in the franchise to include the commander feature.
Each class has its own unique set of weapons and functions.
Players can pick up a kit from fallen players and change classes on the fly, or change classes when waiting to respawn.
The game usually ends once a team's tickets are reduced to zero.
