What is "Irenic"?
Irenic is a medium sized map with lots of cover and several "bases". The main spawn/objective areas are where the sniper(s)/Machine Gun Turret spawn.
Irenic is somewhat unique (Not saying it's the only map like this, because it's not) because it changes with certain gametypes. If you are playing in a symmetrical gametype, Defender base spawns with a sniper. If your feeling up to an asymmetrical gametype, Defender's spawn with the machine gun turret. With these weapon changes geometry changes will also occur to make for more balanced gameplay.
While playing in Slayer, you spawn in one of the two, smaller towers. For this reason, spawns are different every gametype.
Notice:
Please also keep in mind that this map isn't the largest map out there, so keep parties from about 4-10 players. I believe that seems adequate. I haven't had much playtesting, so I am extremely open to suggestions and critiques. Thanks.

Gametype Suggestions:
Irenic has been fitted to play any gametype you want to play on. It's highly recommended for Assault, Oddball, or Slayer though.
As a recommendation, I suggest using the following settings for playing Assault:

One Sided Bomb
Assault Settings > Bomb Arming Time:
3 Seconds, Bomb Disarming Time: 5 Seconds, Bomb Fuse Time: 15 Seconds, Bomb Reset Time: 30 Seconds, Sudden Death: No Limit
General Settings > Respawn Settings:
Respawn Time: 3 Seconds
General Settings > Base Player Traits > Weapons and Damage:
Primary Weapon: Assault Rifle, Secondary Weapon: Magnum/Battle Rifle

Weapons:
Assault Rifles x4
Battle Rifles x4
Sniper Rifles x1
Sniper Rifles x1 (Variable; symmetric gametypes only)
SMGs x1
Plasma Rifles x1
Needlers x1
Brute Shots x1
Covenant Carbines x1
Maulers x1
Machine Gun Turrets x1 (Variable; asymmetric gametypes only)
Frag Grenades x8
Plasma Grenades x4
Bubble Shields x1

Weapons spawns have been made in the most balanced way possible. If you find them unbalanced at all, please contact me with suggestions.

Author's Note: For me, what makes this map especially awesome is this is my first map with major geomerging. I understand that most of the really good maps have tons of geomerging incorporated in them. I have tried on several occasions to produce maps like that. I find it unusually difficult to make any really perfect geomerges. So partly due to laziness and partly due to the fact maps can still be fun without geomerging, I have a very minimal amount of geomerging included in this map. Sadly, this is my first map to include basically-perfect geomerges that actually have a somewhat large affect on gameplay. It's sad, I know. Yet fear not, maps like this can still be plenty fun.

On a side note, I made this map with an industrial feel in mind. It's supposed to look gritty.

Hope you enjoy and happy holidays.

A Few Question You Might Have:

What does "Irenic" mean?

"Irenic" means conducive to, working towards, or act towards peace, moderation, and conciliation. As you might be able to tell, a game with violence and hapless killing is definitely not for peace. You can also see the sarcasm in the file's description on my fileshare.
I have gotten this definition from this website:
irenic - Definition from the Merriam-Webster Online Dictionary

What were your inspirations?

As you might see in the first picture, I was heavily inspired by Last Resort. The Attacker tower in picture number one looks like Camp Froman from Last Resort and even spawns with a Sniper Rifle. In picture number five, you'll also notice a bunker similar to what's next to Camp Froman in Last Resort.
