Scenarios

Seals vs. Terrorists

Basically hide and go seek. One team, is the "Seals". They stand somewhere, and wait a certain amount of time, while the other team, the "Terrorists" goes and hides. Then, the "Seals" go look for the "Terrorists" and try to eliminate them first. A great scenario, for learning when to move up, and checking your back.

Capture the Flag

Well, you capture the other teams flag. You can also, have a flag in the middle, and take it to the other teams base, which is really fun, and challenging. A fun idea, also, instead of people getting killed, have "Medics" on the team, usually the guy, with the pistol, or the crappiest gun, whichever applies. The "Medics" can heal people that are dead. They have to bring the person back to base, and counts to a certain amount of time (15 seconds is good). If the medic is shot, he goes back to base, and counts (10-15 seconds) then he is back in.

Death match

Eliminate the other team.
