The map with a link to the gametype can be found here. Beware, this map contains no interlocking or advanced skills. I realize this and would appreciate it if nobody pointed out information I am aware of. I am somewhat of a forge n00b, but that doesn't automatically mean all of my maps are horrible. I have read the forge 101, and if I make more maps I'll try to integrate the techniques found there. Anyways, here's the description from Bungie.net, cuz I'm lazy.

This is an update to the map inspired by a previous map made by Mark3dm4n and SQUIRE YOUNG and upgraded by Mark3dm4n and myself. SQUIRE posted the original a little while ago, but the version was not completely finished and the gametype not quite ready.

I have done more work with it and I am fairly sure it is ready for download. The basis of the map is the first battle of Star Wars episode 4, A New Hope. The attackers spawn in a room followed by a hallway where they wait for about 90 seconds. With them is "Darth Vader," who wields an energy sword, has x2 overshields, has the Force (regenerating grenades), and, of course, has his trademark black suit. The other attackers have white armor and must protect Vader as he makes his way to the escape pod room of the ship to secure Princess Leia.

After 90 seconds, a fusion coil spawns allowing the attackers to blow a hole in the hull of the Rebel Blockade Runner and enter. They then follow a series of teleporters until they reach the escape pod area. When the Vader reaches the end of the area, the Empire wins. If the Rebellion can hold the attacker off for five minutes, they win. Both sides spawn with assault rifles and plasma pistols (would've made it plasma rifles and pistols but for some reason I couldn't make them spawn with plasma rifles), and there are Sentinal Beams scattered across the map. There is also a beam rifle in the attacker's spawn area.

There are two issues I want to talk about. First off, the third room can get a bit confusing. Once you get off the elevator and go down the stairs, you will enter room nuber 3, which has 3 teleporters. The one furthest to the left takes you directly into room two, and is used by the attackers to get to room 1 quickly at the start of the game. The center one takes you to a vantage point on the attackers as they enter room 3. The third and furthest to the right takes you into room four.
The second issue is teleporter camping. there is not much I can do about this, you just have to trust the people you're playing with not to do it (I know, impossible)

There's a youtube video explaining the map here. Here's some screenshots, too, because I know you all want those ;)

Constructive criticism is appreciated.
