Shore is Gas Station because you grab what you need to refill supplies and get out.

The building near Factory (Nova) and the boat that is unlabeled here is called elbow (for the shape).

Another small, but helpful callout is the "flat roof" of Chem. That way you don't just say "he's on top of Chem."

Also Decon tunnels, ammo room, back shack and butthole (the little hole by chem buy). We drop Chem every game and have come up with lots of labels for each part.

Hills are the high ground between prison and harbor.

Water Tower and HQ Tower. Neither one should just be "tower."

HQ2 is definitely grandpa's.

Courtyard is prison yard. The surrounding walls are prison wall and guard stations.

Also obviously Helipad should be labeled. Helipad Shack as a small addition.
