Easy ones: Mirror armor. Mirror shelter. A dog with zapper on him (Imagine him running around the playing field and people running like all bejeezus to get out of the way :) ) Hard Ones: Surveillance Cameras around the playing field with a base commander to point and shoot them. Proxy Bombs that include a flashbulb for extra suprise. GPS tracking of team members on your pda. VERY Hard ones: Some kind of huge freakin' Death ray. I dunno maybe something that sprayed you with tuna fish.
