Dimension Force is a vertical shooter by Asmik. The game puts the player in control of a military helicopter on a perilous mission into the heart of the enemy territory. Things get quickly out of hand and enemy's tanks and planes soon give place to prehistoric beasts and tentacle mutant monsters. Power-ups hidden inside large planes increase the amount of damage the main weapon can inflict and secondary homing-missiles can be added to the mix. But the meat of the game lies in an unusual zoom option. Stages are divided into two alternating phases.The shooting phases feature a classic vertical shooting gameplay where waves of enemy planes typically fly and come at the player arcade style. The Technical phases, however, feature a zoom option activated with the controller's shoulder buttons. During this mode, enemies are layered at two different altitudes and switching from one to the other is at the heart of the gameplay. Some stages and end of stage bosses can usually only be defeated at a very-low altitude where buildings and other towers become deadly hazards. The game offers several play modes and the shooting and attack phases can be played separately or tied together.
