I've been asked to talk about this game after mentioning it on another thread.
I'm currently playing it on my PS3.
This is a hybrid stealth /action /RPG game. It has echoes of the games such as Splinter Cell, mixed with the Thief series. I'm only really in the early stages because I haven't had much chance to play this week, but so far its going well, and I'm enjoying it
You can basically opt for a full-on 'all guns blazing' combat style, or at the other end of the spectrum you can go out and out stealth. Apparently it is possible to go right through the game without every killing anyone, just by stealth. I've not tried it, but I'm assured it can be done.
I'm going for a middle way of stealth, but being willing to take down enemies by sniping if necessary. And, frankly, it does seem to be necessary, there are a lot of bad guys!
The story is a futurist conspiracy theory type thing, with shady corporations, corrupt government officials, dodgy politicians and so on. Voice acting is adequate, and the cut scenes reasonable with our being anything sensational. I'd categorise the graphics as being decent.
As for role playing elements, that centres around the 'augmentations' you can get - essentially these are implants that improve your character. So you can choose to sharpen stealth, tech, hacking, weapons, defence etc. To be honest its light on the role playing elements, its mainly a stealth- action game.
It's not fully open world, although once you get out of the building that is a tutorial you do have free run of a decent sized city. And there are quite a few side quests that you can pick up from characters around the streets. So its possible to play in a number of different ways and paths - but at the end of the day it is, I think, impossible to get anywhere without following the main quest
So that's a bit of summary. Ask questions if you like. i'd give it a solid 7/10, which might go a point higher if the story starts to get more interesting. I bought it to pass the time until Skyrim, and its doing its job quite effectively
