A great classic!
A lot! Indeed it is a lot like International Karate - even the music is pretty much the same (although, as Jim noted, IK never came out for the PC). I used to play this one for hours on my XT...
The graphics are spectacular (especially when considering the time period), the controls are decent, the music is very well done for PC speaker and is very catchy. Most importantly, the game itself is extremely fun to play!
It's very repetitive, but then it's from 1986 - what did you expect?
The Bottom Line
A real classic for the XT. I like this game and so should you!
