DOS Games Discussion

[Guest]

I have spent more than 2 months already searching for keywords, descriptions etc... but no luck so far.

The game i'm looking for is very old (late 80's) and the funy thing is i'm not sure if it was a "ninja" or "samurai" name... 2D, single character, action game. Not a fight/tournament type ! There was a single level, some kind of a lab-building; a kind of rocket reading a label "colonel smthing", some bad guys. There was a time limit (15 or 30 min.) and the level ended with you escaping on a bike. I remember there was some kind of code, broken into pieces scatered all over the level. There was an underground too, i remember i tried to make a map but i changed my pc and the game was lost... forever

Anyone can help. I think i gave a pretty good and definite description.

Oops. Altough it's asumed by default: The game i played was on PC. (dunno if there was a nintendo version)
