Contra Force is a run-and-gun-style shoot-'em-up video game released by Konami for the Nintendo Entertainment System in 1992 in North America only. It is a spin-off of the Contra series and the third game in the series released for the NES (following the home versions of the original Contra and Super C). In contrast to previous Contra titles, which featured sci-fi elements, Contra Force centers on a modern task force who must fight human terrorists instead. The game was originally scheduled to be released as an unrelated game in Japan titled Arc Hound (アークハウンド?), however that version was canceled and instead Konami localized the game for a North American release as a Contra spinoff.

Crisis Force (クライシスフォース) is a vertical-scrolling shooting game released by Konami exclusively in Japan for the Family Computer on August 27, 1991. As Konami's final shooting game for the Famicom, the game was developed to push the hardware's specifications to its limits and utilized Konami's custom VRC4 chip (previously used for the Famicom version of Gradius II) to allow for four-way scrolling and large bosses. However because of the game's late release during the Famicom's lifespan, a year after the launch of its successor the Super Famicom, Crisis Force did not achieve the popularity that Konami expected. The player controls one of two fighter ships piloted by Asuka and Maya, a pair of twin siblings descended from the ancient civilizations of Mu, who must save the world from a breed of artificial monsters from the lost civilization of Atlantis. The main feature of the game system is the player's ability to transform its ship in one of three different forms, each with its unique attack method.

Cyberball (サイバーボール, Saibābōru?) is an Atari Games arcade game of 7-man American football, using robotic avatars of different speeds, sizes, and skill sets. The game replaced the standard downs system with an explosive ball that progresses from "cool" to "warm", "hot", and "critical" status as it is used. Players can only defuse the ball, resetting it from its current state back to "cool" by crossing the 50 yard line or by change of possession, whether through touchdown, interception or fumble. A robot holding a critical ball while being tackled is destroyed along with the ball. The robots also possess finite durability. As offensive units are tackled, they wear down, finally issuing smoke and then flames after a number of hits. A flaming robot will explode when hit, thereby fumbling the ball. Players can upgrade robots with faster and more durable units using money bonuses they earn during play. Players select from run, pass or option plays on offense, after which the computer presents four individual plays from which to choose. On defense, a player can select short, medium or long defenses, and then select a specific defensive scheme. The standard Cyberball cabinet consists of two monitors, each with two sets of controls for a maximum of four players, but Atari Games released single player and two player versions as well. The standard configuration allows single player, two player cooperative, two player head-to-head or four player head-to-head play. Playing with two teams of two persons opened up a new dimension of gameplay. Computer controlled avatars ran offensive patterns in very specific ways before reaching their assigned passing spots. Human players, however, could exploit the fact that a number of offensive plays started with identical formations. By choosing one play, but moving their avatars in imitation of a similar but different play, the offensive team could disguise their intentions before suddenly breaking for their assigned pass locations. This offensive flexibility forced defending players to quickly recognize plays and move to break them up by rushing to what they guessed was the intended passing spot. Most often, the timely use of the defender's turbo, a short-term speed boost usable once per play, would determine whether the play resulted in a missed pass, an interception, a long gain, or a score. This ability to improvise in four player mode built the popularity of Cyberball, leading to many tournaments across the United States for a period of time. Cyberball was released for the Nintendo Entertainment System in 1992 by Jaleco. Tengen intended to release it unlicensed, but Jaleco purchased rights to publish it first. It has also been ported to other platforms, including the Commodore Amiga and Sega Genesis.
