Guacamelee! Super Turbo Championship Edition

The quickest way I found to get this was in caverns del pollo, run past the save point and past the teleporting head thing then fight your way down to the 8th floor, there will be 2 skeletons rolling around .. You also must quickly roll around to get behind them coz they will strike you quickly. Once both skeletons are close together quickly punch them as so they can not hit you.. Once both are gone the achievement will pop! I had the skeletons trapped up against the wall..

Arenas are simply enclosed matches against a set number of enemies, challenges which you'll find all throughout the game. Simply dodge the attacks and dispatch the threats without taking damage to nab this achievement. You'll want to do this early in the game against weaker, less threatening creatures, but this should come naturally as you play through the game. If you've already beaten the game, the first room in Caverna del Pollo pits Juan against four basic skeletons who won't pose any trouble. The nearby save point and ability to replay this arena make it a good spot to grab the achievement.
