I was busy this weekend so probably only got 6 hours or so to play and didn't complete it. Not sure how far through it I was but I'd gotten to the 2nd yellow zone area when you get on the monorail and managed to get Hearts and Minds to 100% there.
Graphics wise it does look decent, thanks to Cryengine and as I understand it, has had numerous patches to improve performance since release. It ran great at 3440x1440 at the highest settings. Wasn't quite hitting locked 100fps on my X34 monitor, but was averaging around 75fps.
Gameplay wise, it seemed very easy. I did die a few times, but in terms of capturing places often you can just sneak around and get to the 'gas wheel' without even really coming up against much in the way of opposition. I didn't use the motorcycle much unless it was needed for a 'puzzle' (I say that in the loosest sense of the word) as you can run everywhere so quickly, particularly once you unlock most of the outfit 'boosts'
In terms of characters and story though, I didn't find it particularly engaging. All the resistance people are pretty much just horrible 2D archtypes and I didn't really feel like a freedom fighter. I was so uninterested in the setting that I got to the point where I wasn't reading journals I found, which fill in the backstory.
It has some nice ideas, but I think they weren't really developed well enough and some of the gameplay elements are a bit half-arsed.
Tempted to pay £18 to complete it, so it wasn't terrible or anything. Just the definition of a nice looking, completely average game.
