This is Mafia. I created this game to match what I used to play on Coagulation in Halo 2.
This is a new version of the original mafia map. It is very similar, but the bugs have been straightened out, and some of the features have been redesigned.
It is similar to Cops and Robbers, but the cop arrests the Mafia members for doing something wrong. Official Rules are below.
The gametype allows for the Mafia Member to be killed and turn into a cop, which makes teaming up on the last man standing fun and challenging, as the last man standing also runs at 300%. The custom powerup gives you a max of 150%.
The sequel to Mafia, Mafia 2, is available here

One rule that is helpful: NO GUESTS ALLOWED, except if the party leader has a guest. You must have a microphone, so that you can give orders if you're a cop, or tell a cop that you are going to jail. If you don't have a microphone when you play this game, it does not play correctly, and chaos erupts.

"Mafia v2" Map Variant
"Mafia" Gametype
This is best played with 4-6 players.

How the game works
Mafia spawn up in their sky base. Cop spawns in or outside the Police Station (The Blue Base). The Cop must watch for them to do something wrong, and go arrests them. He can use force if necessary.

Locations:
1) The Jail is located in the Red base, and the teleporter to the jail is located on the left side of the Police Station. To be released from jail, the cop can remove the crate from the teleporter in the middle of the Police Station with a gravity Hammer.
2) Extra weapons are located in the hallway in the Police Station that needs to be opened with the button.
3) The Mafia Base is floating in the sky, and can be flown up to with a new elevator system. Just walk into the mancannon, and it should launch you up far enough to move forward onto the platform.
4) Another small Mafia base is located in the back area of the map, just use the mancannon to jump up onto it.
5) Drugs are located through the teleporter in the back area of the map, past the red base, on top of the second small Mafia base.

Basic Rules:
1) No Driving off the roads,
2) No carrying "drugs," (See below for list of drugs)
3) No attacking cops or killing other Mafia Members.
4) Mafia members may not use banshees.
Drugs are:
1) Plasma pistol-Marijuana
2) Magnum-Cocaine
3) Needler-Crystal Meth.
More rules:
1) Cops may never attack a Mafia Member unless that person is trying to assassinate them, or are being defiant.
2) Cops may ask for people to stop at any time, but only if the person may be not following the rules.
It IS possible to break out of jail, and it can include the death penalty if the escapee is found by the cop. It is much harder now with the update though...
3) The last man standing can be killed for no good reason, because the last man "injects himself with steroids" to run at the increased speed of 300%
4) All players cannot see the names of their teammates until they are close, so from a distance, a cop using a custom powerup will show up in red armor instead of blue. Creates a sort of undercover idea, and allowing anyone to run faster with 150% running speed.

Here is a changelog from the original version:
1) New elevator. Still a bit buggy, but I will be working on trying to fix it more. I might just add more man cannons to make sure you get up it. There is one problem, don't go DOWN the elevator. It gets you stuck for a while, and it's hard to get back up or out. Overall, I'd say it works better than the original, and gets you up to the Mafia base almost every single time.
2) Fixed Jail. The jail has been fixed to not only look better, but work better. The barricades have been smoothed out, and cannot be opened, there is no big box at the end of the hallway, it is an actual barricade now.
3) Angled garages. The garages on the Mafia base have been angled downward, so that it doesn't do as much damage when the vehicles fall. I'll be tweaking this more and more to get the correct angle for each vehicle to hit correctly.
4) More weapons in the weapon room. Explains itself
5) A staircase to the Wraith. The Wraith belongs to the Police, but there has always been a problem getting on top of the box. Now there's a small staircase to the top.
6) Fixed drug room. The drug room was completely redone to make sure people won't escape jail through it. It also been made so that there is one way in and out; the teleporter. It can't be blocked, so no more hiding in the drug room.
7) New outside Mafia base. It's up in the air, so you need to launch up to it. This is usually just used to go into the drug room through the teleporter.
8) Fixed a lot of the overall aesthetics.

For anyone wanting to check out Mafia 3, it is on my file share. I probably won't post it on Forgehub, as I am lazy and don't want to take to time to post it. It's on Sandbox, so you will need the Mythic Map Pack.
