EPICENTER
Bomb has been a gametype of much debate in Halo 3. The gametype was acceptable in Halo 2, but without notifications that the bomb is being armed, it didn't transfer into Halo 3 well. With the lack of notifications in mind, Epicenter was designed to play the best Halo 3 can offer for a bomb game.
I also wanted to create a new design, yet keep it very familier to MLG players. It is a 2 base, symmetrical map with 2 lines of symmetry just like Onslaught. Because of this, Most of Onslaughts callouts work perfectly and will help you jump right into this map and feel like home. However this fast paced arena has some interesting curve balls you must learn. To start them off, there is a Active Camo that spawns bottom mid 2 minutes into the game and then every two minutes after that. Camo is extremely powerfull and absolutely must be timed and controlled if your team expects to win. Also, there are mancannons at the back of each teams base used to get the bomb as far away from your base as possible. It will take some practice to be able to throw the bomb in, but it should require some skill to perform as to not make defense too easy. There are carbines at each top A and top B towers along with two plasma rifles at the bottom of each base.
The bomb itself must be armed at the top of the opposing teams base. The map is also setup for all other Team/FFA MLG gametypes and a version of Land Grab using MLG rules. I'll post links to everything you will need to enjoy the map thoroughly at the end of this post.
Here was the sketchup concept of the map, you can see from the pics it has gone through some layout changes and alot of added geometry to make it much more playable:
Map Style:
2 Base Sym w/two lines of symmetry.
Gametypes supported:
2-8 Players
Weapons/Powerups:
4 BR's - 10 sec.
2 Carbines's - 90 sec.
2 Plasma Rifles - 120 sec.
4 Frags - 30 sec.
4 Plasmas - 30 sec.
1 Invis - 120 sec.(Not at start)
Pictures:

Here are two overviews looking at Red and Blue bases. Also has a great view of the center structure.

Here's a view of A tower. B tower is identical.

Here is a view of Red base, Blue base is identical.

Inside each base looks like this. There is a mancannon at the back of them which the Bomb can be thrown into and launched across the map. This is a great tactic to use to technically "Play bomb" if your team is down and the opposing team is pushing in. Here you can see me throwing the bomb in.

And lastly, this is a picture of me arming the bomb. It is located at the top portion of each base very visable to all. This is very important for it to play well on Halo 3 because of the lack of notifications. The bomb arm point has two indicators, this allows for strafing while arming the bomb.
Please make sure when playing customs on this, everyone gets a chance to run around on it and possibly practice with the mancannons. Please DL and come back with some reviews. Also please note, the MLG Bomb gametype is not an official MLG gametype, however it is the mostly widely used and accepted Bomb gametype used for MLG. Also MLG Land Grab was created by me. It also uses all MLG rules just with Land Grab in mind. I tried to make this map a step forward in as many directions as possible for the MLG community and hope you guys enjoy it.
Wanna also say thanks to all the people that helped make this map possible. Had alot of testers and alot of people that gave some great feedback. Also thanks to _TaK_ for helping design the epic center(pun intended) and Baron for coming up with the map name.
