Author's note:

Ok, this one was famous for several things. Firstly, it was quite a short game, making it a game many could actually complete. Secondly, it offered similar gameplay to the more popular 'Commando' game that was so well known at the same time. It was a little more free-form in nature, which is one of the things I liked about it.

I also liked that you could choose either a stealthy, or guns-ablazing approach, and both had their pros and cons. Oh, btw, the premise was similar to the movie, 'Rambo: First Blood Part II', in that you had to rescue prisoners, escape to Thailand etc.
