I remember when I tried this game for the first time...naturally I was way too young for it at the time. One of the first comments I made was "OH MY GOD, WAS THAT AN EYE FLYING AROUND??!!". I was hooked.
The brilliant graphics, with the dark color-scheme of browns and grays, sets the mood perfectly. The player is launched straight into the action, with only about ten meters of dead space before you can start blasting people to smithereens. Seriously; you receive a bazooka within the first 30 seconds of the game! How sweet is that?!
The only thing that bothered me now and then was the difficulty, which would often lead me to get chopped up, squashed, blown up, fried, or all of the above. This would usually prompt me to get lazy and use the good ol' "dipstick" and "chojin" cheatcodes, followed by a plethora of gibs and explosions at the hands of the drunken missile. Good times.
This is the perfect type of game to play with your impressionable younger brother on dark winter nights - aaah...memories.
