Classic Turtles battle Chewbacca, Worf, Judge Dredd, and Spock.
The turtles get 4 hours of prep, and the sci-fi team gets 25 minutes. The teams start 100 meters from each other, in an urban environment. No morals.
Turtles have their normal weapons.
Judge Dredd: machine gun, steak knife
Spock: lirpa (not allowed to use the mind meld or nerve pinch)
