Some random silliness Iāve done on the tank drone, re-tested on the semi-current version:
-Killing them with loose caltrops: works. You pretty much need to set a large area with caltrops if you want a good chance of destroying them, but it works. A single caltrop does surprisingly good damage against them.
-Goo pits. Turns them into a blob. The chances of having a tank drone spawn near a lab is pretty dang low, so having this happen without any debug is unlikely, but the goo pits work on them.
Also tried a few more silly things:
-Chainsaw Lajatang. Kills them in two to three hits. 13 strength, decent melee skills, but somewhat encumbered by clothing. The tank drone will get some hits in with the flamethrower and tazer, especially since the chainsaw lajatang has a horrid hit chance.
-Barrett and .50 ammo. Two critical shots. Can be done in broad daylight. Can shoot them down before they get in range to shoot the rifle, but they can shoot the grenade launcher.
-100 manhacks. All manhacks die. They canāt damage the tank drone.
-Shoggoth. Tank drone doesnāt seem to use the tank gun. Grenade launcher, rifle, flamethrower and tazer not enough to kill shoggoth. Shoggoth gets near and wrecks the drone.
