Capture the Flag
This mode is very simple. Your goal is to steal the enemy's intelligence briefcase and bring it back to your Intelligence Room. You can still capture the intelligence even if your team's intelligence is missing. To return your intelligence to your base you must defend it for 60 seconds from the point it was dropped without an enemy touching it. If an enemy manages to grab your intelligence, even for one second, the timer will restart to 60 seconds. In a standard game of Capture the Flag, the first team to capture the intelligence three times wins the game. Capture the flag has no visable time limit, but the time limit can be imposed by the server you play on. When the time limit runs out, Sudden Death will occur.
Capture Point
Your goal in Capture Point is to stand on your enemy's point long enough to capture it. The more team members you have on a point, the faster it is captured. Scouts capture points twice as fast as other classes. If you are capturing a point and an enemy enters the control point, the area will stop being captured until the enemy is killed or steps off the point. Most Control Point maps force you to capture a point in a specific order, to enforce this, the game locks the control points you are not allowed to capture until you are allowed to move on.
Territorial Control
This mode is similar to Capture Point except each team controls three territories of a map. Each round, the teams will attempt to capture an enemy territory by capturing their one control point. The team that successfully captures the point or wins in sudden death will gain control of the territory, then a new round starts. A winner is declared when a team has control of all six territories. When a team has only one territory remaining, that team is forced to play on defense only. If the team manages to defend the territory for the alloted time, they gain control of an enemy territory and play continues. In the event of a stalemate, no territories are gained or lost.
Sudden Death
When time runs out and no team has won the game it will result in Sudden Death. When this happens, the same score and capture points are kept and everyone is sent back to the spawn point. There is no respawning in Sudden Death, when you die you're out. To win Sudden Death, you must kill all of the members on the enemy team, capture the intelligence enough times, or capture the enemy's last control point. There is still a time limit in Sudden Death. If time runs out in Sudden Death and no winner is declared, the game is a Stalemate and the game declares you all losers.
