In a galaxy blah, blah, blah.

The Death Star is a casual map built around a VIP gametype called "Rebel Scum". This map works well with 4v4, and I bet would work well with more, but 8v8 might be a bit crowded. The map is basically just the Death Star, with 3 platforms which the rebels use to launch their attacks. The gametype is HIGHLY suggested as it makes the map not just playable, but adds some novelty too!

First off, the Gametype.
Rebel Scum is based off of a VIP gametype. The object of the game is to either get 50 points first, or just more points then your enemies. There is two rounds with each round lasting three minutes or when the VIP dies.
Scoring goes like this:
Every kill gets you 1 point.
Killing the Vip gets you 5 points.
Every kill the Vip gets earns 2 points.
Every "target" the Vip makes it to, earns 10 points!
There are obviously two teams, the Rebel Alliance and the Empire.

The Rebel Alliance has two types of Characters:

The default character is a rebel trooper

The Rebel Trooper is always in his orange jumpsuit, starts with a plasma pistol and a needler.
He has NO radar and sheilds DON'T regenerate!
He can use vehicles.

The other Rebel Alliance player is Luke Skywalker (The VIP)

Luke is also in an orange jumpsuit, but enjoys 2x overshields!
He also starts with a lightsaber (sword) and plasma pistol.
Luke is a Jedi, therefore he can sense enemies around him (The force)
He also runs abit faster and does 150% damage and can operate vehicles.

The Empire
There are two types of characters for the Empire.
The stormtrooper

Stormtroopers always come in popular white armour and start only with Plasma pistols.
They have no radar, no sheild recharge but had 10% leech ability.

Darth Vader

Darth Vader is in traditional black attire and enjoys greater shields than anyone.
He moves VERY quickly, does MASSIVE damage and has radar.
Whatever Stormtrooper gets the power-up first, becomes Vader.
There is always only ONE Dark lord of the the Sith, and his powers last for 90 seconds.

The gameplay is simple. All the Empire starts inside the DeathStar, and most will spend the entire round there. The rebels start (respawn) in the crypt, and teleport to one of three platforms up in the skybox (Where the Death star is). The rebels must reach two desitinations (vip checkpoints) for maximum points. The first is the control panel, to de-activate the stations sheilds. (Located top floor of the Death Star). After the Vip makes it there, he must return to the hanger and fly under the Death star and up the maintenence shaft till he reaches the power-core. (That's the second checkpoint.) Sure, you can just go for kills, but getting the checkpoints earns you 10 points EACH, so its well worth it.

Ok, I know that this Death Star MORE resembles the one used in the original Star Wars and NOT the one that was used in Return of the Jedi. I know that in the original Star Wars they didn't fly into the death star to blow it up. I'm certain somebody would've pointed that out! lol.
Also, this map took awhile, but it's still not perfect. There are a few rough spots (I'm making a sphere out of odd square pieces), and the very bottom of the sphere isn't perfectly round. I ran out of pieces, so it was either an interior or finish the bottom. I chose interior.
