How about an Underwater map? Ive been thinking about this lately and i have realized that the scuba helmet isn't getting much use, nor the navy tac helm. To better implicate them and a new form of combat possibly add a spear gun that shoots through water, and have a map COMPLETELY submerged. For decoration i imagine wrecks of machines Like those on Barren. and maybe small air pockets etc. Thanks for considering!
OOF. We wouldn't even have to update to 1.13 for this if we keep the same mechanics of our current underwater mobs for the IR V.3 update. just have to re-texture the mobs. I could see this working on wz.
Underwater maps are always great ideas. However, if you want water pvp, there are plenty of maps to accommodate you. Castaway is probably the best for scuba, just hide under the bottom of one of the ships, peek at the back for air, and it provides cover. Other decent maps for it include Rig, even though you lack cover on it. Overgrown is also good, but very limited.
