Played through it until the 3rd boss fight a few years earlier but got my augs messed up so I ended up giving up. Glad I came back, played through again, and finished it up. Throw vending machines at peoples heads or sneak through air vents. I go for stealth when I can but sometimes you need to fight and its pretty good, cover based shooter feels a bit weird to me because I haven't played a lot of games with that mechanic; but, you get used to it pretty quickly and you end up using it often for peeking around corners in stealth or staying safe in combat. The boss fights are underwhelming especially since there is no way to do them non-lethally, unlike the entire rest of the game. If you are completely combat based then the boss fights aren't the worst, but the lack of choice is not great. Energy management feels a lot more convenient than in the 2000 Deus ex and it changes how you use some abilities, like camo, you can use them more often and recharge back a full battery. The places, you go to, look really good and usually have a lot of entrances and paths to choose between. Ended up with the pacifist Taggart ending.

The dlc is a mission in the middle of the campaign that shows what happened to Jensen as he crossed the atlantic on a freighter, it's pretty cool and I had no idea it wasn't in the game from the start until I was told, it fits very well into the game.
