I was expecting more "cyberpunk" stuff like robots and spider tanks too.
I was thinking of drones with Predator-like "thermo-optic camouflage" that we can use for recon and maneuver into position as weapons that will strike targets on command - allowing for a kind of a "trap" / tower defense-lite style of attack.
Maybe in DLC I suppose.
Edit: I'm not opposed to "guns and knives". I'm opposed to there being ONLY "guns and knives". Come on. It's 2077.
