Haha I know I said I wouldn't do another "themed" map but I really like how this one turned out.
It's called "Special Delivery," and while designed as an Extermination map, it could easily work as a defensive gamemode, like Hostage rescue.The idea is a shipping/loading area with some semi trucks and boxes scattered around. (The trucks look a bit odd in-game, but I think overall the visuals and balance of the map came out how I wanted.) One team is situated with a strong defensive position, while the other team might be given a rocket launcher or more troops, and has to breach the compound. The main building has 3 entrances, each with their own defensive quirks. However, there aren't many windows, leaving Defending team with very little control of the exterior. I see Offense with longer-ranged units, so they'd have a lot more control of the relatively exposed open area in the right/bottom half of the map.
Assuming team composition doesn't have to be equal, I see Offense being equipped with a rocket launcher, a shotgun, and a pair of machine guns, while defense might have a grenade, and maybe two shotguns and a machine gun? I'm not sure, in any case, it was a lot of fun to make!

Edit: Fixed some pathfinding issues and made exterior walls a bit thicker.
Also, I realized that I accidentally swapped cover and walls on that last map, so here it is again, with the colors fixed and the grid removed. I playtested it too (Thanks for showing me how, Joa7000!) and although the walls are a bit on the thick side, it seems to play fine in terms of pathfinding. I see a team comp of 2 machine guns, 1 shotgun, and a grenade launcher on each time, set around the "dining table" as an interesting start position for this one.

@Aron I like the metro map! I can see lots of flanking happening since the map is so wide and horizontally oriented, so you don't end up with an annoying defensive stalemate. Very cool!
By the way, if anybody is interested, I am totally down for playtesting custom maps against each other. Could be lots of fun!
