I think human revolution be a strong buy if you be look for something outside of the call of duty-style shooting gallery . dxhr be a place of character , decision and consequence , as much as it be a place of bullet and bloodshed . it be one of the more rewarding action game that I have play in several year and a worthy companion to the original . the story be a engrossing techno-thriller potboiler , where you be never quite sure who you can trust , or for how long . some alliance be brief , and turn of fate can come unexpectedly . thing be not what they appear to be at first , and people be not always who they seem to be . the more you uncover , the higher the stake seem to get . but you do get clue about where thing be go to go , if you hack enough computer and get you hand on the right people and the right document . even the side mission inform you about the game world and how you character be view by other ; sometimes a hero-in-waiting , other time a potential contract killer . it be up to you to confirm they belief or prove they wrong . after all , you have great potential for both good and evil with you `` augmentation , '' prosthetic that re not just mechanical assistance but machinery \* better \* than flesh and graft to you body ; replace lung , eye , and heart , not to mention you limb . the higher capacity that this give a person -- and the effect that it have on the perception of they very humanity -- will be a run theme throughout the game . dhxr also hearken back to the old Splinter cell , with a side of metal Gear Solid . like those game , you can not run into a room gun blaze . you have to strategize by either pick people off surgically , or avoid they altogether . you 'll need to get password and keycode to get into secret area , and the environment be highly explorable -- there be a distinct lack of paint door and arbitrary obstacle , and a complete absence of invisible wall . so go ahead and wander down that corridor that lead away from you objective , because you may find a useful weapon or valuable piece of information . the area have a variety of alternate route , some of which you need special ability -lrb- call `` augmentation '' -rrb- to access . you 'll need to hide the people you have take down , because another person sight they can set off a alarm . if the person you have take down be unconscious -lrb- you get a variety of non-lethal approach to combat -rrb- , then they can be revive . firefight use a cover-based system that put you in a third-person , over-the-shoulder perspective . you can blind-fire or aim around corner . and you can lob a variety of grenade . you can hack robotic gun turret sometimes and turn they against you attacker . it work pretty smoothly without make you feel like the game be do all the cover work for you . as far as production value go , the visual be behind the curve , but this do mean that more computer will be able to handle the game without many performance issue . the voice acting be generally very good , although Adam Jensen may be a acquire taste . it help I to pretend he be basically Clint Eastwood transport to the future . the ambient music be incredibly atmospheric , although the main theme be use heavily , and you may find it repetitive . sound effect be also polish and vary . if I have any complaint , it would be for the spike in difficulty for the `` boss battle . '' there be few of they , thankfully , but you 'll probably find yourself reload many time before you finally crack it . it be not ninja gaiden maddening , but it do evoke the same kind of frustration . there be also a lot of back-and-forth when wander in between mission , without really any landmark to guide you . it be a bit easy to get lose or hit a dead-end .
