Carrier Air Wing, released in Japan as U.S. Navy (ユー・エス・ネイビー Yū Esu Neibī?), is a 1990 side-scrolling shooting game released for the CP System arcade hardware by Capcom. It is the spiritual sequel to U.N. Squadron, released during the previous year. As with the original, players chose any one of three different jet fighters and battle their way through ten enemy-packed stages. Other ideas carried over from U.N. Squadron include the shop, which allows players to buy weapon and shield upgrades for their jet fighter between stages, and the energy bar, which is replaced by a "fuel bar" which starts full at the start of each stage and decreases as time passes with some fuel lost each time the plane is damaged.

Commander Keen is an episodic video game developed by id Software in the early 1990s. The series focuses on the adventures of Billy Blaze, an 8-year-old boy who travels through space and assumes the secret identity of "Commander Keen". The series was successful at replicating the side-scrolling action of the Nintendo Entertainment System Super Mario Bros. games in DOS. The cartoon-style platform games are notable for their pioneering use of EGA graphics and sharewaredistribution, and they were some of the first games by id Software (who went on to later develop Wolfenstein 3D, Doom and Quake). The games were also exciting to thePC gaming community of the time because of John D. Carmack's smooth-scrolling graphics game engine, which first allowed smooth side-scrollers on PC by only redrawing the screen's elements that changed frame-to-frame.[1] Most of the Commander Keen games were published by Apogee Software, an already established DOS shareware game publisher. Tom Hall is Commander Keen's designer and the creator of its universe. Commander Keen Complete Pack, a collection of the officialCommander Keen games (excluding Aliens Ate My Baby Sitter and Keen Dreams) was made available on Steam on August 3, 2007. Keen Dreams was ported and released for Android enabled devices on June 10, 2013 on Google Play.
