1. Bloodlusted unarmed H2H deathmatch in a karate dojo
2. Gunfight in empty Penn Station; both get Berettas with unlimited ammo
3. Melee in an automechanic workshop
4. They must hunt each other down in NYC. They get no initial prep or resources besides an hour to read up on their opponent. Who hunts down who?
