Has the classic vibe of a stealth game, massive maps, and an alright story behind it all.
Pros:
Lots of potential with maps.
I've a mere 4 hours and I have only completed the first mission on "Goblin" difficulty (which is the hardest of the difficulties. The maps are incredibly large. full of many possibilities of your sucess or demise; be it the convinient tunnel, heavy objecting hanging above a guard, malfunctioning machines, gob in a box, the common ledge, the miscalculation of one's eyes, and much more.
A game for nitpicking.
There's quite a handful of enemies on each map, you can keep to the shadows and aim directly to the objective, or you could just run aimlessly assassinating every living thing you can find. While I could have skipped a good 90% of enemies without killing them, I simply could not pass on finding and assassinating EVERYTHING. l got a lot more of this game trying to clear an entire map over simply running towards the next loading screen.
Smooth Graphics.
Cyanide certainly knows how to make a good optimized game with some nice graphics. It's no next gen, but I'm sure many of us care for gameplay over graphics these days. I'd say I ran at a smooth 60 FPS at the highest settings, with very little tearing. I'm using GeForce GTX 560 Ti, non overclocked with 12 RAM.
Good Handling.
Controlling Styx is quite seamless with a gaming mouse. The amount of his abilities make a gaming mouse quite useful, but for those that don't own such luxuries can change any keybind through the options. I attempted playing it with a 360 controller, and I would say I much prefer Mouse+Keyboard combo due to easy access of key binds. Let's just say Styx isn't the best at grabbing ledges sometimes...
It's better than Thief.
That poor poor franchise.
CONS:
The AI
This is a stealth game, so I constantly had many "Really?" moments. The enemy AI is no different from any other stealth game and pretty much comes in two ways: the first being "Guard notices you, you run to hide, guard can't find you despite being a few inches away with a very obvious glowing orange tattoo" or the second which is "Guard notices you, you engage, dodge, parry, counter, dead guard, move on". I noticed I went through a lot of the second way through my first playthrough on Hard. To combat the non-stealth feeling and linear gameplay, I simply switched the difficulty to the highest which is "Goblin". I would not recommend any other difficulty if you truly want the feel of a "stealth game". Getting one shot can be quite annoying, but hey, what kind of "Master of Shadows" would get caught in the act of murder?
Bugs like a Bethesda Game.
I have only experienced a few bugs, but none that made me reload. Any bugs that I did encounter were in a "Bethesda" way. Floating bodies, launching dead bodies after a kill, stretching rag dolls, teleportation when assassinating, and minor clipping. None were game breaking, and is clearly something all games these days face. I'm sure patches are to come.
A "Bioshock Infinite" feeling.
Those familiar with Bioshock Infinite might get a retaste with Styx's abilities. While Styx has several abilities, you might find yourself only using a few of them in most situations that aren't forcing you to use them.
Overall opinion:
It's definately worth the $30, but I HIGHLY recommend you play on the highest difficulty to get the real stealth feeling. You can easily make the game last a few hours if you simply run through the enemy and go for the objective; make the most of it by slaughtering everyone in the area and collecting relics/coins. Abuse the amber! Amber powers can easily be forgotten if you don't use them often, they can be quite helpful on many maps! Exploration is important. There will always be more than one way to kill an enemy. Sometimes there's ways of clearing an entire map by the push of buttons...Keep your amber vision lit... Oh and, I hope your virgin ears are ready for the constant f#cks and sh#ts both Styx and NPCs spray out like a rainy day.
I give Styx: Master of Shadows an 8/10.
