You have to give Doom credit: if there was ever a game that would spark a creative frenzy in the gaming community to try and create the next killer app that would try and topple the originator, Doom was it. When the Saturn was hitting its shaky first year stride in 1996, there had already been a LOT of copy cats flooding the market. Fox Interactive decided to try their hand at the clone tool and attached one of their most precious movie licenses, Alien, to the mix and see what happens. The gamble paid off, and gamers got a fun romp through Ripley's worst nightmare.
Players take on the role Lt. Ripley as she makes her way to space colony LV426 to investigate and crash an alien egg laying party. Along the way she’ll take on face huggers, aliens, dog aliens, adult aliens, even evil corporate bastards trying to keep the acid dripping monsters alive. If you’ve ever wanted to take your frustration out on a corporate entity, now’s your chance.

Referencing Doom means we’re talking a First Person Shooter (FPS) type experience, and it’s a kicker of a journey. All of the requirements of early FPS games are represented; shot guns, pistols, big weapon, huge weapon, hordes upon hordes of targets, hidden doors, lost items, and the uncanny feeling you’re about to get slimed. Thanks to the Saturn's 2D abilities, the game looks a smidge better than the PlayStation version.

The game does a great job bringing the player into the environment, except that it does it a little too well at times. This experience is dark; really, really, dark. So dark that at first glance you think your TV’s brightness knob is busted. With a little fiddling, you can get the brightness to a more respectable and playable setting without ruining the mood of the game. While the levels are polygon based, the creatures and human enemies are sprite-based, and both do a fine job. I’m actually surprised how well the level visuals held up after all this time.

Essentially the only kink in the armor is that certain level layouts make no sense, and will have you running in circles for a while. Speak of, the Saturn controller's D-Pad sometimes doesn't feel right when trying to turn corners. I found myself getting stuck here and there, but overall it's nothing big enough to detract from the game. 

Considering its relatively easy-to-find status on the buying side of things, for the few bucks it commands you owe it to yourself to check it out.

Just watch out for the face huggers.

• If placed into a computer, tracks 2 through 13 are all music files and can be played / copied to a music player.
   
• There are three text files with "ACCLAIM ENTERTAINMENT, INC." written in them on the CD.
   
• Assuming it was some weird effort to keep online bulletin board posters guessing, all three versions of the game (PSX, SAT, PC) have similar Cheats, but the passwords to unlock them are all completely different.
   
• The alien face-huggers (xenophobes) literally jump at your face and slap their underside to your entire viewing angle. Perhaps this could be considered the absolute original "Tea-Bagging." ^_^
   
• This is essentially running off of a Doom-like engine, complete with walking 'sway'.
   
• Probe also worked on the original Die Hard Trilogy.
   
• If you're ever bored, glance over every Acclaim or LJN release you own. Damn near every screen shot is guaranteed to be accompanied by a sentence ended with an exclamation point.
   
• The designers took an interesting liberty with the Alien blood. Their acid based life stream is still active even after you kill them. If you step over / on a corpse of a defeated foe, you'll take damage from the spilt blood.
