So I was just running around exploring the good old city and then all of a sudden I came across this mech.

I was staring at it a bit wondering what it might potentially be for then it attacked me.
I went "Oh shit" and hit it back but then it just stopped completely. Right clicking it gave no info.
Anybody know anything about what I'm dubbing Rogue Robot?

Interesting...to be fair I haven't had the game loaded up for too long and really explored...but I do like that awesome robot. I assume it's like the hero NPCs walking around. There for flavour and to fight villains perhaps?
