Here are some scenarios that can be played during matches where the playing area is somewhat limited in size.
 
Team Death Match - Both teams are spaced equally distant from a house or structure. The objective of this match is to rush to gain control of the house or structure.

Last Man Standing- This Free for All match is usually played with a short time limit and low ammunition loads. The last man standing wins.

Left For Dead- In this scenario, 3-5 players in an entrenched defensive position are left in the middle of a field. The other players then attack with the main objective of eliminating the defenders and capturing the position.
