Disclaimer: Do not buy this game if you do not own a gamepad. The mouse support is about as bad as it gets. I use kb/m whenever possible in third person games and I had to use a gamepad for this one.
Enslaved is a well-written and satisfying-but-simple spectacle fighter with a heavy story emphasis and some minor puzzles. It is a post-apocalyptic adaptation of a classic Chinese novel "Journey to the West." There are several nods to the original story, such as the names of the main characters which may interest those who have read the book.
The writing is excellent for the most part and acted very well. The game manages to be both serious and humorous while telling the story and rarely feels out of place. My one issue is the way that the two main characters Monkey and Trip meet. The meeting should be the biggest source of conflict in the entire story, yet it is glossed over and forgotten within a minute. It reminds me a lot of the criticism aimed at Tomb Raider 2013 and Far Cry 3 for how quickly those main characters got used to killing people after leading normal, peaceful lives up to that point.
Gameplay is pretty simple and definitely nothing groundbreaking. The game is a simple yet satisfying spectacle fighter with simple one-button traversal mechanics. You also need to solve a few basic puzzles to make it through some levels. It is quite easy even on hard difficulty. Unfortunately the game makes use of seemingly randomly-placed fixed camera angles that can easily confuse the player and will sometimes make your character immediately walk back through a doorway after entering a room. The other big issue with the camera is during combat itself. It likes to jerk the camera around randomly every time you attack and zoom way in so it's impossible to keep track of enemies other than the one you're attacking. It may also cause motion sickness. It's a stupid design decision chosen just to make the combat more flashy, as seems to be a common problem with spectacle fighters.
The game has a nice art style, but average last-gen console-quality graphics. I find that this is enough to hamper the art style in what should be a very beautiful game, which is very unfortunate. It still has its moments, but it would be an absolutely gorgeous game if the developers had put any effort into the PC port.
Speaking of the port, it's just about as lazy as it gets. The mouse is treated like a joystick and is given a deadzone when you go into aim mode, just like Dead Space. It's basically useless and I found it unplayable. Graphical quality is limited to low/medium/high though it thankfully has a separate toggle for motion blur which looks even more fake and ugly than most games. There are no graphical enhancements for the PC version. Button prompts always show controller buttons even if you don't have one plugged in. The game has a custom mouse cursor, yet the mouse doesn't work in menus. The one good thing about the port is that the game uses Unreal Engine 3 so it runs very smoothly and will handle 120/144 Hz flawlessly with only a minor config tweak.
So while it's far from a perfect game, mostly due to poor and outdated design decisions and a lazy port, it's quite fun and a great story experience.
The Premium Edition on PC also includes the Pigsy's Perfect 10 DLC. It turns the game from a simple-but-satisfying story-focused spectacle fighter into a sub-par stealth/cover shooter starring a fat, disgusting, misogynist pig on his quest to build a robot girlfriend. Seriously what were they thinking? Thankfully it was short.
