Gameplay
Vertical Force is a vertical-scrolling shooter. The player pilots the starship Ragnarok, tasked with destroying a malfunctioning supercomputer on the colony planet Odin to prevent Earth's annihilation. The Ragnarok can withstand multiple hits and shoots down enemy fighters while avoiding projectiles and obstacles. Power capsules dropped by enemies enhance the ship's abilities, such as a wide shot, piercing laser, or shield; collecting more capsules further strengthens these. A key mechanic is the ability to switch altitude into the background, letting the player evade obstacles on different planes and causing enemies to alter their behavior. AI Drones found in stages assist in combat, each with different weapons; they can be damaged and stored in a reserve box for repair and later redeployment. Drones also function as smart bombs to clear all on-screen enemies. The game consists of five stages featuring starfields, mechanical bases, and tunnels, each ending with a boss that sometimes requires altitude switching to damage. A recurring mech-like miniboss named Bratt appears in most stages, learning the player's abilities and growing stronger. High scores can be saved to a table but are erased when the system powers off.
Development and release
Hudson Soft developed and published Vertical Force for the Virtual Boy, releasing it in Japan on August 12, 1995, and in North America on December 1, 1995, published by Nintendo. It was Hudson's only other Virtual Boy game besides a port of Panic Bomber. The game uses a red-and-black color scheme and parallax scrolling to simulate 3D. Originally planned as a third-person rail shooter like Space Harrier, the team shifted to a vertical-scrolling shooter due to anticipated similar games for the console. It was shown at the 1995 Winter Consumer Electronics Show under the working title Shoot'Em Up!. Hitoshi Okuno directed the game, with music by Shōji Tomii and Minoru Endō. Vertical Force was re-released via the Nintendo Classics service on May 14, 2026.
Reception
Vertical Force received polarized reviews from critics. Some praised its 3D effects and detailed graphics, while others criticized its lack of originality and the difficulty of seeing enemy projectiles against the background, attributed to the Virtual Boy's limited color palette. Electronic Gaming Monthly criticized the graphics for obscuring enemy bullets, and GamePro disliked the unimpressive enemy designs and lack of originality. Next Generation was most critical, lambasting confusing stage layouts, poor 3D effects, uninspired gameplay, and hard-to-spot projectiles. Jeremy Parish found bullets hard to track due to hardware limitations, calling it sloppy compared to Hudson's Star Soldier series but a decent effort for the hardware. Famitsu felt the game felt dated and criticized the graphics for making enemy shots hard to see. The Electric Playground called the gameplay bland and lacking originality, unfavorably comparing it to Xevious and 1942, and noted a generic soundtrack and graphics. Conversely, GameFan praised it as a must-own game, highlighting its gameplay, challenge, and 3D effects, calling it one of the system's best launch titles. Game Zero liked the multi-layer depth mechanic for distinguishing it from other shoot 'em ups, calling it one of the system's best launch titles and one of Hudson's best shooting games, also praising the soundtrack and detailed graphics. Electronic Gaming Monthly compared it to TurboGrafx-16 shoot 'em ups and found the multiple-depth mechanic interesting. Parish called it the most graphically detailed Virtual Boy game and a decent addition to the library. Vertical Force was selected for the Spacewar!: Video Games Blast Off exhibition at the Museum of the Moving Image in New York.
