Power - Turn on power and forge pack-a-punch.
Orbs - (Shoot all orbs)The first orb can be found between two computers next to the power door in the Particle Accelerator. The second orb can be found right in front of the stairs to park-a-punch, and you will have to crouch to see it on the other side of the grate. The third orb can be found under the pack-a-punch stairs, next to the box in the zombie window, and it is the very top left corner of the room. The fourth orb is behind a few pipes which you can find when you get on top of a generator next to the stairs up from the bottom area of the Particle Accelerator. The final orb can be found when standing on the Particle Accelerator on the top left of the wall on the other side of the stairs to pack-a-punch.
Crate - Now you be teleported into the Dark Aether which you will have to go down to the pack-a-punch and see the zombies carrying a crate. Wait till that's done then go back to the pack-a-punch and open up the crate.
