This is a map designed, crafted, and now posted by me, BadCompany Brik.

Alright, overview. Here you go:

Fairly basic map. Mostly because the entire playspace had to be crafted out of 1-way shield doors. You see, on Reverb, you stick to the ceiling.

Obviously, I can't really capture that effect without motion, but you'll have to take my word on this one. Don't do what those guys are doing though, everyone has concussion rifles so clustering is definitely a bad idea.

The two ways of killing people are either by launching fools off the edge with your concussion rifle:

Or taking 'em out from behind:

Why would I include assassinations? Wouldn't that just cause people to spend all game running in circles trying to get behind someone? Well, it adds a risk to the commonly used strategy of turning around and boosting yourself with your own concussion rifle. And looking really awesome too.

The spawn is just a simple little area with grav lifts to get you into the action.

These fellas are going to be there awhile,

2000% damage resistance, 25% damage, so you deal so little damage that you couldn't conceivably kill someone by conventional methods (barring assassinations), but you still do a tiny amount of damage, so you get credit for kills when people fall to their deaths.
There is a shield door between the ceiling and the spawns. Stop trying to spawn kill.
Try not to go up lifts right after your friends, feet do occupy space, and in this case, the space that you should be passing through in order to stick to the ceiling.
Look up before you go up the grav lifts, you may want to figure out where your enemy is before he knocks you off the edge with his Concussion Rifle.
Coordinate strikes with your teammates. If you find you keep getting teamed up on, then tell everyone on your team to stop, choose a lift, and then go up at the same time to even the odds.
It's possible to play this with any amount of people. It just turns into an enormous mess with more than ten. Not that there's anything wrong with that.
If you try to join Gold Team, as amazing as it is, don't say I didn't warn you when you spawn alone in the Coliseum. Red vs Blue only.

There's more than one supported gametype. I went ahead and set it up for 3-Plot, Crazy King, and (of course), Grifball! Just disable AAs from your local Grifball variant and have a blast.

The link to Team Slayer should be at the top along with the map link.

Also, if you liked this you may want to check out Frito Bandito 7's Phlow. It's another nice take on ceiling combat.

Share, and enjoy.
