Last man standing
For the trigger happy within the group this is a fantastic game.
Basically the last person to be shot wins.
Capture the flag
This is an old favourite.
A flag is placed at each base and you must defend it whilst working out how to capture the opposite flag.
The rescue
A team member has been captured and you must work out a strategy to rescue them.
The gauntlet
You and your team must retrieve a briefcase with stolen documents in it, unfortunately it is situated somewhere within a narrow corridor which is probably easy to ambush?
VIP and False VIP
Your security team must protect a VIP whilst deploying a false VIP to distract the attacking forces.
