Springtrap goes first this time

You play as: Springtrap, on the attacking side
Goal: clear each corridor and open the next door
Controls: arrows to move, Spacebar to attack
Weapons: fists, then crowbar, pistol, gun and axe
Cost: free in the browser

In Springtrap's Rampage the main character is finally the one doing the hunting. Press the Spacebar to use whatever you are holding. The task is to get through everyone in your way. Move through the dark rooms and pick up knives, pistols and other things to deal with your opponents.

At the start you only have Springtrap's fists, but a crowbar, a pistol, a gun and an axe all turn up later. Each room is a long corridor guarded by people in matching uniforms. Get through all of them to take the new weapon and open the door to the next room.

How to clear a corridor cleanly

Pick up every weapon you pass, even one you will not use - it denies it to them
Fists are viable longer than you expect, but only against single guards
Range beats damage in the narrow rooms
Springtrap's own condition is the story here, and the game does not explain it - FNAF 3 does, and there is a FNAF 3 download if you want it offline
