Reciprocal is a map I've been working on for quite some time. The original idea popped into my mind about 3 months ago and forging started soon after. The map didn't take very long to forge, but a few testing sessions proved there were flaws in the map design, weapon placement and spawns. I went through about 2 months of tweaking the map to get it to where it is now, which I believe to be the best it can be. But there's always something I could've missed or something someone has a different opinion on. If this is so, please bring it up in a comment after playing the map.

Reciprocal first started of as a design for a Capture the Flag map, Multi-Flag particularly. I began thinking of some maps that played well with Multi-Flag and started to study them. Here's a few key notes I gathered.

-Plenty of routes around the map
-More than one entrance to a team's base
-Placement and choice of weapons and equipment that will help both to defend and to attack.
-1 neutral power weapon up for grabs in the middle to give one team a little advantage for a short time to prevent a stalemate.
-Long lines of sights in areas that would be taken as a quick route to capture a flag.

In Reciprocal, I tried my best to incorporate these notes into the map, and I believe I have done a good job.

Major Weapons and Equipment:
Sniper (Defender's side; 1 spare clip; 180 seconds)
Overshield (Defender's side; 180 seconds)
Shotgun (Attacker's side; 0 spare clips; 180 seconds)
Active Camo (Attacker's side; 180 seconds)
Rockets (Neutral; 0 spare clips; 180 seconds)
Mauler (Both sides; 0 spare clips; Symmetric; 120 seconds)
Needler (Both side; 2 spare clips; 90 seconds)
Bubble Shield (Attacker's side, Asymmetric, 60 seconds)

Here's some screenshots to get you familiar with the layout and the callouts. I honestly don't think the screenshots do the map justice, so I was trying to get a video for it. Unfortunately, the guy who was doing my video just couldn't get it done, so I'm going without it...

Special Thanks goes to all my testers who stuck with this map during it's dreadfully long testing stage, you know who you are. I probably never would've published it if these guys didn't keep on asking me when the hell I was going to post it.

ehh, might as well post this too... Teaser pic for my next map:
