Deus Ex: Human Revolution (Deus Ex 3) returns with all the brilliance that embodied the original 2 games in the early noughties. But, it is in fact a prequel to those games, set some 25 years before the first Deus Ex, when development of bio-mechanical augmentation by a few elite and powerful companies threatens to destabilize society. The main story follows Adam Jensen, a private security officer for one of these companies, as he attempts to figure out who is behind recent terrorist attacks on his company.
In terms of gameplay, this is where Deus Ex: HR excels. There are multiple methods of completing objectives, and this can include a complete stealth approach (there is an achievement for completing the game without killing a single enemy), traditional FPS (shoot anything that moves), or a mixture of both. And this works for the majority of the game, but the only let down are the boss battles - in these you are forced to confront a specific character and take him/her down (don't worry, this won't harm that achievement I mentioned), but these are the only occasions that the game forces you to take a specific approach, and thankfully they are few in number.
There are RPG elements, and as you progress through the game, you're able to upgrade your abilities to focus on specific traits. For example, you can prioritize augmentations that either improve your combat ability or your hacking abilities while neglecting others, and how you choose these augmentations will largely depend on your style of play.
So impressed was I with the game that I decided to play through it twice, once as a traditional FPS, and the second as a stealthy pacifist - both times the game felt different due to my differing approach. Total play time came to 36 hours for both playthroughs.
