Xeno Crisis is an arena shooter in which one or two players take control of battle-hardened marines embarking on a deadly mission to confront an alien menace and get home alive! Run and gun your way through thousands of adversaries as you explore the devastated research outpost, searching for survivors, and ultimately facing the origin of the outpost's demise. Outpost 88 is divided into seven distinct areas, each being randomly generated with each play, meaning that your strategy must evolve on the fly if you're to succeed in your mission. Collect dog-tags from vanquished enemies to upgrade your equipment between areas and look out for special weapons which will give you a momentary advantage.

Warblade is a shareware computer game for Microsoft Windows and OS X, written by Norwegian developer Edgar M. Vigdal. The Windows version runs well on Linux under Wine. It is also available for retail in the App Store for iOS devices (in iPhone/iPod Touch and iPad versions). The game is a 2D space shooter in the vein of the perennial classic Galaga. It is a rewrite and modernization of a popular Amiga shareware game, Deluxe Galaga, which was written by the same author back in the mid-1990s. Where technically possible, the graphics and sounds are respectful to their Amiga origins.

Inner Circle Creations gave birth to Alien Rampage (also known as Ravager) in 1996, with the help of Softdisk Publishing as publisher. Alien Rampage is a 2D side-scroller with large animated sprites and multiple layers of parallaxing backgrounds. You are a lone angry alien dude with a bad attitude. You crash landed on an inhospitable planet, and thus you set out to get back to a ship so you can leave this horrible place. To make it, you'll blast hundreds upon hundreds of nasty creatures, enemy bounty hunters, and you'll use some pretty impressive weaponry to do it. You'll also get to buy power ups and get help from the goofy local troll-like natives, to solve puzzles. The gameplay consists of running, jumping and shooting, with a big emphasis on shooting. The action is very gory, and is akin to DOOM in 2D.

Use creative combat tactics and skill shots to earn high scores as you teleport through city streets and rooftops in an awe-inspiring ballet of bullets. Tear apart your robot foes and use them to fend off the enemy onslaught. Unlock, customize and test weapons before taking on challenges that put your newfound skills to the test!

Overcome an ever-expanding threat that might have already seeped too far into the core of humanity itself.

Moon Patrol is a side-scrolling shooter that puts players at the controls of a six-wheeled moon rover that can jump and shoot. The goal is to move through the entire course as quickly as possible while shooting enemies for additional points. Cannons are mounted on the front and top of the vehicle, and both fire simultaneously when the fire button is pressed. Rocks, mines, and pits in the course prevent you from just holding to the right for maximum speed. Rocks and mines can be shot, but pits must be jumped. Some enemies fire shots that create new pits in the course, forcing players to react quickly.

Hybris is a vertically scrolling sci-fi shoot 'em up for the Amiga.
