Gang Beasts

This is a very easy achievement to win. Start a local game with you as the only player, selecting Melee mode and the Girders level.

To the right hand side of the level is an orange chute which builders use to drop rubble and waste through on a building site. Simply run off the side of the building and drop through the chute. The achievement should pop immediately.

Go to the stage Girders
On the right side is a row of buckets
Simply jump down through them to unlock this

Load up the level Girders. Go the right side [specifically the orange tube AKA chute] and fall through it, for the achievement.

Set Game Mode = Melee
Wins = 8 (this gives you maximum amount of tries before taking you back to main screen)
Stage = Girders

One of the easiest achievements in the game, head over to where the orange chute is on the right and drop down into it.

The Achievement guide below will walk you through this achievement and all 18 others achievements in the game too including an easy method for getting the most difficult one in my opinion (Sit Down achievement).
