Strategy X © 1981 Konami.
Advance to the base and destroy Emmortalian.
Even Patton would spend all his quarters attempting to advance through the four attack levels (and base) of Strategy X, Konami's latest tank attack video game. The tank commander's life isn't an easy one.
Part 1: Defend yourself against rotating cannons.
Part 2: Watch out for attacking Jeeps.
Part 3: Careful! Here come attacking and shooting tanks.
Part 4: Rotating cannons again, but this time against a moving background.
Part BASE: Destroy bricks, watch out for colored bombs, don't disregard rotating cannons either and move until you reach an octagonal mine. Destroy it.
Aside from an on-going battle, he has to watch out for obstacles and rough terrain. Brick walls destroy tanks, although they can be shot away. TNT, rather nasty stuff... explodes when shot, but destroys all objects in the area. Stay off pink backgrounds. If an alien base is found and destroyed, advance to the next level of difficulty.
Strategy X. There's never been a war game like it. It blows minds, and quarters.
