Lightning Fighters, released in Japan as Trigon, is a 1990 scrolling shooter arcade game by Konami. It is commonly compared to Raiden, though the two games were released very close to each other, and they were both meant to compete with the works of Toaplan. Though Lightning Fighters has become an obscure arcade-only title, Konami has referenced it multiple times over the years. Gradius Gaiden features a boss modeled after the ship and weapons from the game, and Yu-Gi-Oh! cards such as "Trigon", "Delta Tri" (based on the mentioned Gradius Gaiden boss), and "Dragon Laser" also represent the game.

Data East used footage from the film Harmagedon to create a laserdisc video game titled Bega's Battle. It was released in June 1983. In the game, the player to take on the role of the robot Bega (Vega) whose goal was to stop the invasion forces of the alien Varga (Genma), while also rescuing his three friends who had been kidnapped by them. Even among laserdisc games Bega's Battle has become somewhat rare because many of the machines were converted into Cobra Command machines as part of a discount deal offered by Data East in exchange for the internals of the Bega's Battle arcade cabinet. Similar to Astron Belt, the game used the footage mainly for backgrounds, while the actual gameplay was a shooting game with sprites laid over the video. Bega's Battle also used brief full-motion video cut scenes to develop a story between the game's shooting stages. Years later, this would become the standard approach to video game storytelling. Bega's Battle also featured a branching storyline. The Twin Galaxies world record for Bega's Battle was set by Steve Harris (later the founder of Electronic Gaming Monthly) on July 18, 1983.

Released specifically for Naxat Soft's Summer Carnival of 1993, Nexzr Special is a collection of short stages and modes that share their basic gameplay system and visuals with Nexzr. The regular mode introduces familiar regular enemies and a few new bosses. The "Carnival Mode" contains Score Attack and Time Attack modes, both requiring the player to focus on attaining the high score rather than just surviving. For that reason the difficulty in these modes is more forgiving; they allow more continues and have more generously placed power-ups. These modes also offer more destructible objects on the screen, as these specifically serve to increase the score.
