The gameplay is kind of shot to hell. Shoddy A.I.(either hyper-competent or completely brain-dead), loose controls, a gunplay system that is ENTIRELY reliant on your skill points in said guns instead of a mixture of the two and pain in the ass hacking minigames that get harder the MORE points you put into making hacking EASIER. Yeah, the game scales to your current character level too, I never knew that. Don't EVER try to boost your AP using a cheat device, you'll just fuck yourself over as everything will be maximum difficulty while you don't have the armor and weapons to back it up. Also, the game encourages stealth but then flops you into a straight up boss fight a lot of times. The best way I've found to go through the game is to focus on Pistols in weapons exclusively, and Stealth really. And the graphics are pretty shoddy too, worse than Mass Effect. And it relies on checkpoints for it's saves, very big no no in RPG's from basically a veteran developer.
Despite all this however I played through it around 3 times to see all the permutations of the story and interactions with the characters. The character interactions, while not phenomenally voice acted are GREAT and every character will react differently depending on which choices you pick in dialogue. Hell there is a secret encounter you can only get BY making certain dialogue choices until a specific part of the game. And while not everything is explained even in the end, there is a lot going on in the story to make it interesting. Give it a shot if you find it cheap, like $5 or less.
