Power Core

"A long time ago, this facility was powered by using a single Core. Now, the Power comes from elsewhere.. Asset 10 Players, S11S"

Updated - Version 3.1 is available, ran through what Rifte Gifle said and thought a few things did need changing. Amended the spawns and made it less likely to be a chieftan and a camo brute. Also removed all flame grenades, camo brutes now have a mauler and a radar jammer.

My Comments
Power Core is a unique Asset map. Due to it's inferior size compared to Dune Asset maps, Power Core is everything when it comes down to Originality in Asset.
It stands out because of three simple things:

It's built in the skybox.
It's only playable on a small area of the map yet it plays amazingly well.
The Power Core itself is a key feature in the map.

The Power Core is a cylindrical shape passing through both levels of the map. It uses switch mechanisms and timed spawnings to eventually open a doorway which allows Virgil (the asset) and the ODSTs to escape via the hornet.
