Gang Beasts

You need to survive after almost dying in the Grind stage
You might get lucky while going against AI in wave mode
You can also do this in melee mode in which you'll be alone
Climb into the grinder on either side then keep jumping (A) until you're out
Just keep trying until it pops

This is my full 100% Achievement Walkthrough, all solo methods

Easiest way for this is:

- Local game:
- 1 Controller
- Melee
- 2 wins
- Grind

When the level starts, just go to the right. jump over the railing onto this grinder (Try to get into the center of the Grinder). Then hold the stick left & continue to press A/Jump until you get back over the railing. The Achievement will pop almost immediately. Takes about 5-10 seconds.

I have done this on multiple tags & it has worked every time.

Set game mode = Melee
Wins = 8 (this gives you maximum amount of tries before taking you back to main screen)
Stage = Grind

You just need to hop into the grinder on the right using and mash the button again to get back out.

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) .
