This game is great ! If you like a little challenge, fast paced (and oh so satisfying) gameplay and stunning, cyberpunk themed, environment then stop wondering and get this game you won't regret it ! While hard there's nothing impossible imho, the checkpoint are never far from where you die making deaths at most a bit annoying but never punitive, you really do learn from each of them. And then when you get the best way to execute your plan and clean the room it can create some sick moves worth a place in a movie ! I'm giving it just 4 stars cause while great it isn't perfect. Your character can sometime feel like he's sticking too much to the walls when you don't want him too and some other light flaws in gameplay but it doesn't ruin the experience.
