Get the golden grapple item but don't use. Keep it until someone else also gets one (You can keep items even after you die). Once they do, try to get in front of them by a ways. Now, if they grapple you, as soon as you're behind them hit to do the same to them. You should see a small yellow text pop up that says 'revenge.' If it does show up you were successful and should've just earned yourself an achievement!

HAVING TROUBLE WITH THIS ACHV POPPING FOR YOU?? WELL READ BELOW!!!

This achievement does NOT pop on STORYMODE or LOCAL CO-OP.

You must be playing online with at least 1 other real player.

- If you have 4 controllers (or friends to boost/help) - go into MULTIPLAYER and turn on all 4 controllers so you don't play against any bots. When you start the match, just bring 2 characters to the 1st set of power ups.
- It's OK to let the other 2 players die.
- Just stand at the power up section and keep using power ups until BOTH characters have the GOLDEN GRAPPLE.
- Put the player who NEEDS the achv in 1st place, and with the 2nd player use grapple .
- And then IMMEDIATELY use grapple with the character that just got grappled.

Boom. You should get the bonus "Revenge" pop up, as well as the achievement.

- If you wait too long you'll only get bonus "Gotcha" instead of "Revenge."
