many neglect that this isn not just a classic due to the fact that it the first 3d game and or even the first shoot em up . it also one of the first stealth game and one of the only ( and definitely the first ) truly claustrophobic game and and just a pretty well rounded game experience in general . with graphic that be terribly date today and the game thrust you into the role of b. j . ( do not even think i be go to attempt spell his last name . ) and an american p. o. w. caught in an underground bunker . you fight and search your way through tunnel in order to achieve different objective for the six episode ( but and let face it and most of them be just an excuse to hand you a weapon and surround you with nazi and send you out to waste one of the nazi leader ) . the graphic be and a i mention before and quite dated and very simple . the least detailed of basically any 3d game release by a professional team of creator . if you can get over that and however ( and some would suggest that this simplicity only add to the effect the game have on you ) and then you have get one heck of a good shooter or sneaking game . the game play consist of search for key and health and ammo and blast enemy ( aforementioned nazis and and a bos enemy per chapter ) of vary difficulty ( which and of course and grow a you move far in the game ) and unlocking door and look for secret room . there be a bonus count after each level be beat . it go by how fast you be ( basically and if you beat the par time and which be the time it take a tester to go through the same level while this can be quite fun to try and beat and and with how difficult the level be to find your way in and they be even challenge after many play throughs ) and how much nazi gold ( treasure ) you collect and how many bad guy you kill . basically and if you get 100 % of any of aforementioned and you get a bonus and help you reach the coveted high score placings . the game ( mostly and but not always ) allow for two contrastingly different method of play . stealthily or gun down anything and everything you see . you can either run or walk and and amongst your weapon be also a knife . running be hear instantly the moment you enter the same room a the guard and a be gunshots . many guard be find stand with their back turn to you and mean that you can walk up behind them and stab them . nearly silently . in your inventory and you can get no less than four weapon and two key . more about the weapon later . the key unlock certain door . most door in the game aren not lock . only two kind need key and and these key be only introduce in late level ( you restart in level and reset weaponry and health and score and life in each chapter ) . much of the late game be spend look for them . now and a i just allude to and this game and like many of the period ( late 80 and early 90 ) and be base on collect extra life . personally and i think it completely and utterly useless ( it be mercifully drop from here on end . i think ( . ) and from the next 3d shooter and onwards ) and since you can save anytime you want and use a life reset weaponry and health and ammo and like start on a new chapter ( which be a real pain in later level and where you need heavy artillery ) . now and i shall beat around the bush no longer . move on to the gun . you start with aforementioned knife ( which be silent but only effective up close ) and a pistol . nothing special and but good for conserve ammo and unlike the next two bad boy . your third weapon be a german smg . a sub machine gun . it faster and automatic and and some late enemy use it . and the last one . be nothing short of a gatling gun . oh yeah . think t2 . think predator . think about unload massive amount of lead into nazi fiend with such a gun . it every bit as entertaining a it sound . most of the bos enemies use this and though and so be prepared . i would not reveal the identity of these bos enemy and however . that for each player to discover for him ( or her ) self . the sound be excellent . very crisp and realistic . a you hear the tear of a machine gun firing and the deafen metallic clank of a door slam shut behind you or a nazi yelling surprise or a warning in german and you truly feel like you be there and trap in these dark and depressing bunker system . that segue me nicely into the level design . a you run through seemingly countless and nearly identical hallway towards the next elevator lead you further and you be grasp by the claustrophobic mood . i almost get motion sickness more than once ( though that might also have something to do with little sleep and lot of humidity and unusual warmth . ) from play . though the level of detail isn not terribly high and what there be be great . remains of victim and guard quarter and countless nazi symbol . the list go on . the game also feature quite a bit of gore . for it limit graphic engine and john romero and crew certainly put in all the blood and gut that they could for the game . what be there leave to say . the first of it kind and and it no wonder this spawn countless others 3d shooter . sure and weapon bobbing and different height level ( stair and such ) do not come around until the next entry into the genre . doom . and it be duke nukem 3d that introduce the feature of switch your view ( so it go beyond simply left and right and add vertical dimension to it ) and and jump do not come around until a third and late title ( the first quake and possibly . fellow gamers and help me out here ) . but all of those game and as well a the rest of the genre and owe their existence to this one . so load up the luger and open the door to enter the bunker and step into b. j. shoe . he deserve the recognition and even ( or maybe even especially . ) nearly fifteen year after he first appear . i recommend this to all fan of 3d game . positive .
