Fury Unleashed

** Due to the game being a Rogue Lite I cannot give an exact location to get the achievement ** however I can give you the method I used to get the achievement.

Method :
This will unlock 4 achievements if done correctly.
All you want to do is rush for the exit (which is always located in the bottom right square of the map) without taking damage or firing a shot. Keep sprinting (Hold down RB) and dashing(Push RB in the air etc) and checking the map for your quickest route to the exit. NOTE : touching enemies does not cause damage to you , only if they shoot you or do a melee attack. Feel free to rush past each enemy as quickly as possible to unlock the following achievements:

A Good Start : Finish a page with full health points without using fast travel.
Pacifist : Finish a page without killing any enemies and using fast travel.
Happy Pacifist : Finish a page without killing enemies,taking any damage and using fast travel.
TLDR : Finish a page in 30 Seconds
