Map Description: The imposing towers of this waterlogged installation do little to avert the bloodshed beneath them. 2-8 Players

Gametypes: All gametypes except Invasion are supported, but Slayer, Headhunter, Oddball, Crazy King, Stockpile, and Juggernaut are recommend, in roughly that order. Both teams and FFA work well, and testers said multiteam worked well also. I really enjoy Headhunter on this map.

Cool Story Bro: Reversal started life as an idea I had just before Reach came out. I started forging on Sept 17 and have been playtesting and tweaking the map since then. Reversal is a medium-small symmetrical map, that, in my opinion, plays a very pure game of slayer. I don't mean that in a pretentious, "all DMRs all the time" way either. I mean that the balance between the snipers, rockets, and sword evokes that particular brand of distilled fun that makes Halo what it is. I hope you agree. Now that I've tooted my own horn, it's PICTURE TIME.

A view from offshore.

Here is an overview of the map. The layout is pretty simple, and first time players have no trouble finding the good stuff. http://i183.photobucket.com/albums/x236/superguh007/Reversal%20v1/Overhead.jpg
Mouse over the image for weapon locations. All grenades are x2; the rockets, plasma repeaters, and the dmrs next to the concussion rifle are on the lower level; there are also spare magnums and assault rifles (4 each), but I omitted them because no one cares. Here's the full weapon list:
[Ordinance, Distribution, Spare Clips, Respawn Rate]
Rocket Launcher, x1, 1 spare clip, 180 sec
Energy Sword, x1, full charge, 120 sec
Sniper Rifle, x2, 1 spare clip, 90 sec
Concussion Rifle, x2, 1 spare clip, 60 sec
Needler, x2, 2 spare clips, 60 sec
Designated Marksman Rifle, x6, 2 spare clips, 45 sec
Plasma Repeater, x2, full charge, 30 sec
Magnum, x4, 2 spare clips, 30 sec
Assault Rifle, x4, 1/2 spare clip(s), 30 sec
(2) Plasma Grenades, x3, N/A, 15 sec
(2) Fragmentation Grenades, x4, N/A, 15 sec
Health Pack, x4, N/A, 15 sec

Let's take a tour, shall we? Starting from the outside and working in, our first stop is the back wall. The snipers spawn up here, and it is a popular, but not particularly effective sniping spot.

You can also see the needler on its little platform.

An overview of blue side. The blue team starts under the sniper catwalk in everything except assault.

The "tower, 3 story"s work as makeshift bases, but they are decidedly not the focal point of the map, and they are only used prominently in CTF, Assault, and Stockpile. There's not much in here except a light in the ceiling and a drop down from the top of the base, which gets more traffic.

A look at the concussion rifle spawn on red side. The concussion rifle is a useful counter to both snipers and swordsmen, but usually loses to the average joe with a DMR.

You can also see the lift from the lower room...

...which serves as one of the primary safe respawn areas, but also provides access to the upper level of the map via gravity lift.

There is also a DMR leaning up against the inside of the tunnel.

Continuing on the lower level, we come to bottom middle, the home of the beloved rocket launcher.

It might look cozy down here...

...but with great power comes great sight lines. For snipers.

In smaller games it's often easy to sneak off with the rockets. Once the map fills up, you'll have to earn the magic death machine.

Naturally, there is a side path to the rockets. Blue side gets pretty windows, red side gets a landslide. Here are the windows (poor reds):

Above the windows is the walkway from needler to top middle.

Top middle is home to the dance floor and the sword.

This screenshot is from an older version of the map. As you can see below, there are ramps to the bridge from both concussion and needler.
You'll notice a rather prominent bridge on top of the sword. It has two plasma grenades, above average sight lines, and can be accessed...

...from here. There's a DMR in the little tower.

Again, it's the same thing on the other side, but with rocks.

Action Shots: for those who love pictures.
A typical skirmish in the Blue waterpark.

A fight on the dance floor.

Putting the rockets to work.

Jet packs turn drop downs into fly ups. There is another drop down against the back wall, so jet packs are a popular AA for this map.

...as you can see.

But spacemen are easy targets for snipers.

Speaking of snipers, you might think that with a relatively short respawn time and several elevated positions to pick from that the sniper rifle dominates the map. However, it is extremely difficult to snipe across the map with views like this:

Unless, of course, your targets are merrily rocketing into the aether.

Changelog: for those that have played older versions.

Version 1.0:
-Tweaked several minor aesthetics.
-Added ramps from concussion rifle walkway to center bridge.
-Switched DMR and sniper, sniper is now on back catwalk.
-Updated spawns to support larger teams when necessary.
-Overhauled safe zone / kill barriers: The edges of the map and the two central towers have the same low barrier from before, but everywhere else the height limit has been lifted. This prevents the "Return to battlefield" message from showing when using the lift or jet packs.
-Moved neutral initial loadout camera to look better and reveal sword location for newbies.

Testers: A huge thanks goes out to tester's guild and everyone else that played my map while it was a work in progress.
