Thanks to guesst some aditional information has been added:
This game was made by none other than Jordan Mechner. Jordan Mechner was more an independent film maker than a game maker when he started writing Karateka, hense the reason for the cinematic quality that had never been seen before. After Karateka Mr. Mechner went on to refine his digital story telling prowis producing Prince of Persia and Prince of Persia 2.
An evil overlord has kidnapped the love of your life. You reach his palace on a high mountain and Karateka begins. It was an excellent game when it came out and it still hasn't lost much.
The graphics are CGA, but they still look nice (they don't hurt your eyes), you can easily recognize what's what suppose to be,and so on. It even doesn't look pixelated (which is an excellent achievment). The sound is PC speaker, but not unpleasant and the game features something I think no other game before ever did – CUT SCENES!!!
As the game progresses, more cut scenes appear to give you an update on what's going on deep down in the enemy's stronghold. The enemies get harder as you continue, increasing the challenge.
OK maybe it's a little repetitive – fighting one guy after the next, but at that point they couldn't have done any better. Speaking of fighting, you move with the arrow keys, but to perform kicks and punches you need to use the following: Q, A, Z for high, mid and low punch; W, S, X for high, mid and low kick. I think space is for side step, but I wasn't able to use it in combat.
So what are you waiting for, go on and save your lovely lady out of the claws of the evil lord, before he has his ways with her.
You need to press space as soon as you see the "Brøderbund Software, Inc." credits. If you don't you'll see a message asking you to place the disk in your drive and the game will hang.
