So, here is my first map I have made on Halo Reach, Hydrophobia.

It is a symmetrical objective-based map. Water is enter-able and you can battle in it. Use for cover, or a place to trick pursuers. But, if you do suffer from hydrophobia, there is some land for you to run around on. Or you can just defend for your team.

Basic Summary
You will spawn in an armory with any armor ability that you want. Around you, there will different weapons around you. In the back, there is a hole to drop down into the flag/bomb room. In the front, there is a door to jump out into the front of your base. To the sides, there are bridges leading to the very back of the base. This leads you to a gravity lift that launches you to a nice heavy MG turret on the top.

Weapons in Spawn Room
Spiker x2
Concussion Rifle x1
Grenade Launcher x1
DMR x1
Shotgun x1

Weapons on Map
DMR x2
Sniper x2
Rocket Launcher x1
Gravity Hammer x1
Plasma Grenades ~x6
Overshield x1

As you can see, it is a kind of complex map. It also works better with more people. It is, as I said before, symmetrical.
HOPE YOU GUYS LIKE IT!

Please give me any feedback that you can. Thanks!
