I'd like to say I did the Original Rambo (C64) justice, but while I think this game is a blast, it strayed a bit too far graphically from the original for my liking.
What you get is a game that controls much like the bullet shooter style games of today, but with a scrolling rambo setting. Lots of explosions, some objective based gameplay, and Rambo himself, cheese and all.
It was received very well by the retro remakes community, and my only regret is that I would probably stick to 2D next time for a project like this.
This remake is now complete, and the file can be downloaded from here
