Vertical Force

The player controls a starship, the Ragnarok, that must destroy a malfunctioning supercomputer on a human colony planet before it wipes out all of mankind.

Gameplay is similar to Hudson's Star Soldier series, featuring power-up items that increase the player's abilities and parallax scrolling.

[1] The Ragnarok must shoot down oncoming enemy fighters and avoid their projectiles and other obstacles in stages, and can sustain multiple hits before being destroyed.

[1] Some enemies will drop power capsules that can be collected to strengthen the Ragnarok's abilities, such as a wide shot, a piercing laser, and a shield.

[1] Throughout stages, the player can find small craft known as AI Drones, which when collected will help the Ragnarok destroy enemies, each featuring different weapon types.

[11] Next Generation was the most critical of the game, lambasting its confusing stage layouts, poor 3D effects and uninspired gameplay, alongside it being hard to spot enemy projectiles due to the system's limitations.

[9] Jeremy Parish similarly found the bullets hard to track due to hardware limitations, calling it "sloppy" compared to Hudson's Star Soldier series, although noted it was a decent effort in transitioning the Star Soldier gameplay to the Virtual Boy hardware.

[3] The Electric Playground criticized its gameplay for being bland and for lacking originality, unfavorably comparing it to games such as Xevious and 1942, alongside its "generic" soundtrack and graphics.

[8] Parish said it was the most graphically-detailed game on the Virtual Boy, claiming it made a decent addition to the console's library.
