This map has been over a month in the making and has been thoroughly tested by many different groups of people.
This is an invasion/invasion slayer map built on Montana/Alaska.
I really don't know what else to say so here's some pictures taken from some very recent matches on both game types.

Overview.
The basic story of the map is that a squad of Elites were tasked with the destruction of an entire UNSC outpost.

Not wanting the humans to call for help they attack the communication satellite in an attempt to cut them off from all reinforcements.

The capture points are outside of the actual base simply because as far as gameplay went it was not possible for the Elites to get into the base.

The second phase is crossing the bridge to capture the gate house.
In this phase the humans have a pretty heavy advantage of height and weaponry. The missle turret on the top of the tower to the left (in this shot being destroyed by the banshee) will prevent almost any enemy from crossing unless dealt with by the aforementioned banshee.

The capture points for this phase are illustrated in the pictures below.

One thing I simply had to do was make an exploding door. I had had this idea about two months ago before I had ever built anything in reach forge (and in fact before I joined Forgehub)
I tested it quite a lot on a bridge but it seemed quite illogical for the attackers to destroy their retreat.
After much painstaking testing and researching phased creation/deletion I settle on blowing the door for epic lulz.

Ah the final phase, by far my favorite to work on just because I love building HQ type structures.
(There is a vehicle garage on the back of the base that I forgot to include in the pictures, I will get that in a bit)

The rock spire in the center is a very important cover/ line of sight barrier which serves the dual purpose of housing an assaulting man cannon and creating a wonderful center piece for Invasion Slayer.

The core room. One of the more challenging parts of this map being as it is so small. There and numerous ways in including a secluded rock pathway in the back and open windows on the roof.

The core capture point is just outside of the once existing gate. Sorry I could only find a picture with explosions in it.

I hope you enjoy this map as much as I enjoyed making and tweaking it over the weeks. :)
