The DLC is fine. New heists are alright. The new SMG is decent. There's alot of complaints about the robots but they really arent that bad. They go down within 1-3 shotgun shots or a burst from a full auto weapon. Yes they can explode but there's a solution to that, dont get too close to them. They have an audio queue when they are about to explode so that's your time to run. I consistently beat extreme dif loud heists with 3 ai against the robots no problem. They are tough but not unbeatable or op. I will agree that visually this DLC is offputting for many as it goes from a relatively grounded visual experience to a bit futuristic with the heists/robots. Personally, i think it's a decent DLC. Received it free with the game.
Edit to add: Forgot to mention the weapon skin. I really like it. Easily one of my favorites. Just wish the new SMG supported weapon skins.
Edit 2: So as of update 11.3, the Scudominon supports weapon skins and it looks decent with them.
