Unusual walker with a side view. A little man (Ladd Spencer) with green (red) hair and with a satchel (it's not a satchel, it's his hand connected to his back by tubes) descends by parachute into the camp of the enemy. But he moves in an unusual way - clinging to the ceilings with a cat and pulling himself up (Actually, this is his mechanical arm, hence the name of the game). At the level, you need to find a computer terminal and get the necessary instructions. The level to pass must be chosen on the map, consisting of squares with numbers connected by transitions. Enemy vehicles move along it. The ultimate goal of the game is Hitler's head in a jar, which must be destroyed. The Japanese version is called Hitler Reborn, but in the American version, the title and some elements of the game were censored.
