Prey, baby. I've been playing it for the last few hours, and it is really good so far. It's an immersive sim in the vein of Deus Ex and Dishonored, mixed in with a little bit of dat dere Bioshock, set on a space station full of awful monsters in the year Twenty-Thirty-Something. Also JFK lived to the age of like 115 in this universe. Does that mean anything for the overall story? I don't know, but I can't wait to find out!
I just threw an upgrade point into the physical strength branch of my skill tree to give myself the ability to lift heavy boxes, so I could open a path through a ventilation duct into a space lab, where I sneaked past some enemies, used my GLOO cannon to build myself a staircase of high-tech sticky foam to reach a workstation with the blueprint for a spacesuit propulsion system. I used a nearby matter fabricator to build it for myself, then opened an airlock and zoomed out into space to track down a keycard from a recently-ejected corpse, and I suspect that if you're the type of video game player attracted to immersive sims, that paragraph will be just about enough to get your mouth watering. Did I mention you can... hack into people's e-mails? (I'm in heaven with this game )
So while the sneaking, hacking, keycode-finding, alternate-path-creating antics are straight out of Deus Ex, the Bioshock-y bits come in the form of the big hub-based world you explore, and the slightly heavier emphasis on combat. While you can sneak past most enemies, I don't believe this is a game that can be ghosted, and the stealth mechanics aren't really robust enough for it anyway. I've done a fair bit of bonking these Headcrab-esque enemies called Mimics with my wrench, and this is made harder than I really feel is necessary due to a slow bonk animation, very mobile enemies and what feels like a totally unnecessary stamina bar governing how many bonks I'm allowed. I'm not crazy about this part of the game so far, but I'll see how it goes.
After a really excellent first hour introduction to the world, the game has settled into a fairly standard Bioshock style of progression; go here, whoops the door's locked, better go here to find the key, OK now go there, repeat. The story threads that have been teased so far are tantalizing, to say the least (Chris Avellone is credited as a co-writer), so I can't wait to see how it goes.
EDIT - Oh wait, the music! It's done by Mick "That guy who did Doom last year" Gordon, and it's wonderful. Mass Effect 1 vibes from all this electronica in space.
