So I just finished the first I guess, 'boss battle' of the game, in the tutorial section on the hardest difficulty.
So far, not terribly difficult, only encounter I had to redo a couple times was the 'boss'. But the main thing is to not get hit it seems, dodge/block everything, watch attack patterns, learn when to strike and when not to. (Specializing as the Ranger class)
Game looks good on PC, nothing special, but texture resolution is above average. Runs fine maxed out on a 670.
Similar to War Logs though, you can instantly tell it's a budget title. Animations are janky, voice acting is inconsistent, dialogue writing is inconsistent... but so far, not terrible, not fantastic. I have some other games to finish up first, but I didn't have any qualms with the game to the point where I want to stop playing it, so it's definitely something I'll be playing later on.
It's a much more polished Mars: War Logs, aside from the setting of course.
Oh, another good thing so far is the soundtrack, but that's to be expected from Olivier Derivière, his scores to Remember Me and Alone in the Dark were absolutely sublime.
I think if the game appeals to you or even slightly interests you, pick it up. Do not listen to 'professional' reviews in my opinion, go with your gut, you may end up really enjoying it.
