Area 88 EN+ is a retranslation of U.N. Squadron that keeps the original Japanese name of the game. In addition to the new translation and title screen logo, this hack rebalances the mission rewards and plane prices to encourage the use of the mid tier fighters, the F-14D Tomcat and A-10A Thunderbolt II, which most players skipped before. Both are fun planes that lead to different strategies in the mid game levels.

Additionally, this patch unlocks the gamer difficulty option and changes the firing mode to full auto fire.
