Pack a Punch
Once the Power has been turned on the player will need to activate 2 terminals on either side of the Particle Accelerator Room. Once this is done a Dark Aether portal will spawn in the centre of the room.
The player will now need to activate the Dark Aether portal. Once done they will be teleported into the Dark Aether version of the map. There are 2 possible locations where the part for the Pack a Punch machine can spawn and it is random which one you get each game. The game does make it easier for the player as there is a big icon of a white exclamation mark over the place where the part will be located.
One part location can be found in the Medical Bay inside a small storage room. To get there the player will need to head up to the Crash Site and they will notice that the front of the plane is floating in the air with a portal beneath it. The player will need to spend 500 essence (points) to go down the tunnel. Once at the bottom the part is located in the corner of the room. The player will need to pick it up and then go back to where the Dark Aether portal was located in the Particle Accelerator room, where they will now see the outline of the Pack a Punch machine. When the player interacts with it they will forge the Pack a Punch and then be teleported out of the Dark Aether back into the normal world.
The other part location can be found in the Weapons Lab in a side room. To get there the player will need to head up to the Pond where they will see a tank is floating in the air with a portal beneath it. The player will need to spend 500 essence (points) to go down the tunnel. Once at the bottom the part is located on a box. The player will need to pick it up and then go back to where the Dark Aether portal was located in the Particle Accelerator room where they will now see the outline of the Pack a Punch machine. When the player interacts with it they will forge the Pack a Punch and then be teleported out of the Dark Aether back into the normal world.

Free D.I.E
In order for the player to acquire the Free D.I.E wonder weapon they will need to have turned on the Power and forged the Pack a Punch machine. They will then need to wait till a Megatone spawns in. Once it does the player will need to kill it. Once killed it will drop a keycard which will be highlighted yellow.
The player will then need to head down to the Weapons Lab and place the keycard into the drawer device. This will then open up the drawer so the player can pick up the Scanner device.
The player will now need to train a wave of zombies up in the Spawn Room (Yard) and then take them through the pink bunny door towards the metal door in Nacht. The player will then need to interact with the hole in the wall and this will power up the D.I.E behind the door to suck up the zombies. Once enough zombies are sucked up the player will need to interact with the hole in the wall again and this will cause the D.I.E to blow down the metal door. Once done the player needs to enter into the small room and pick up the D.I.E wonder weapon.
