All Friendships:
Each character has one Friendship added with the "Aftermath" DLC. To use Friendships, enter one of the following button combos (found under "Finishers" in the "Move List") when the screen says "Finish Him" (at mid distance). Friendships are a non-violent alternative to fatalities. Note: If you are in a kompetitive match, you are not allowed to block in the final round to use Friendships, but this is not required in non-kompetitive matches.
