- NPC Wall climbing (not climbing up, climbing around like pillbug etc) This is impossible because 99% of all maps have no wall noding, also a special node would be needed to do so that would potentially break other npcs. I will be making these npc's floor only. If you are making a map that requires this do pm me as there is an illusion thing you can do to sorta simulate it. - Morph ball weakness's There is no morph ball in gmod yet, so most bosses that require or use morph ball mechanics will NOT have any way to utilise these weakness's. Some bosses may not happen at all if they cannot be fought in human form (for example sanctuary fortress's caretaker class drone may not be possible). I will be doing my best to implement workarounds - Portals? They now exist but to a very limited extent - Water Creature spawner? I am not aware of any way of procedural water creature spawning so this is probably not going to happen unless you are playing on a 100% water map and enough people want it. - Visor weakness's and usage see Morph ball weakness's, not gonna happen till it exists. - Wall collision animations There is no way to detect walls with npc's in gmod, so uh no.
