he resist to almost anything (on top of having heavy weaponry), that’s why it’s one of the most hard to kill guys you may find (talking about a fight, not a cheesy way to get rid of enemy).
Thats also why I don’t even try to get rid of them unless I have a laptop (before I would just avoid it …), or during night time.
Tested right now, me against 10 tank drone, night, spawn them at 30 range close together. I run, when close to them i use time dilatation (3k power); they were all dead before it run out but the last one, that put some fire (ended in a big hole that made me falling 2 level down lol, big explosion, hopefully i was able to climb)
Worst case, he react to sound, you may want to hide yourself using something (furniture) and trow stuff to make it move somewhere it won’t annoy you. That’s risky, but if you don’t go close (I don’t remember what range each weapon have), he will only target you will the missile launcher; Just hide & go back further, it’s fine. Do he may be able to run out of missile ammo ? If that so, at this point it would be an easy target.
