Played the first three hours, hated the combat, then I restarted the game to get the first achievement since I missed it, but by doing that I carried over an understanding of how combat works, and the combat ended up playing out a lot better/ I wasn't left with frustratingly low levels of ammo or health.
The game really suffers at points for not explaining its systems well, at least in regards to those initial combat encounters. Understanding that you need to hit and run is kind of essential, and with the awful checkpoints (which could have allowed to gain a feel for the combat) it doesn't balance well, especially considering the first third of the game is combatless.
Having finished the game now the only real issue I have now is the ending, which I guess is in line with the games cynicism but its still disappointing and abrupt. I'd give it a 8/10 as a game, but a 10/10 in terms of uniqueness and as an experience.
