Have opponents to lose points on the Appolips Void
Go to the railgun platform and, when someone comes on one of the two raising platforms, jump. Make sure someone is on the platform or you will lose 10 health, even if you land on them. They will get 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1 to nine. You will get in the lead very far ahead.
