U.N. Squadron

The game is a typical side scrolling shooter, going against the trend of other Capcom shooters, such as 1942 and 1943: The Battle of Midway, which are vertically scrolling shooters. Like other Capcom shooters, the player has an energy bar that is consumed over the course of a single life as the player sustains damage. This trait is highly uncommon among other comparable arcade-style shooters which normally use a system of reserve lives, where one of which is lost upon a single enemy hit. Before entering a level, the player can purchase special weapons or added defenses in the shop. The player earns money to buy weapons by destroying enemy planes and vehicles during levels and, when the level is finished, any unused weapons are converted back into money.

The player can choose between three mercenary pilots: Shin Kazama, Mickey Simon, and Greg Gates. Each pilot flies a specific plane and has slightly different capabilities.

Capcom director Yoshiki Okamoto commented that the game was part of a broader strategy of Capcom at the time to appeal to a wider audience by using established characters from other media, as their original characters could be too niche. In addition to Area 88, he cited games based on Willow and Tenchi wo Kurau as part of this strategy.

In Japan, Game Machine listed U.N. Squadron on their September 15, 1989 issue as being the sixth most-successful table arcade unit of the month. In North America, it was a major hit, becoming the top-grossing software conversion kit on the RePlay arcade charts in February 1990.

Upon its home console release, the Japanese gaming publication Weekly Famitsu gave the Super Famicom version a score of 28 out of 40.
