Don't let the screenshots or "action" label fool you, environmental puzzles are the focus of this game, with some third-person shooting mixed into it.
I personally needed to refer to a walkthrough every now and then as sometimes it was confusing how to interact with certain objects (perhaps what happened to the above poster ^). The sci-fi under-city slum/industrial setting this game has as well as it's level design are IMO it's strong points. It feels like there is a decent amount to them as there are often cramped, hard to reach nooks and crannies throughout them that you need to use drones to access. I'm not going to write a whole review here so I'll stop and say that it's certainly worth a look. Just don't go in expecting the shooter experience you may at first have thought it to be.
