Space Castle

The game consists of 10 missions. Each mission takes place in a vast cavern, with interesting weather conditions. You must explore it and complete the mission objectives -- usually collecting sub parts, rescuing trapped miners, or destroying giant, epic bosses. You can also explore the levels, but keep an eye on your fuel gauge and beware the many hazards!

A freeware early style shmup.

Shienryu is a 1997 shoot-'em-up by Warashi for the Sega Titan Video arcade system later ported to the Sega Saturn.

Gunnail is a vertical space shoot'em up. It's a very standard shooter - very fast action, and many enemies to kill. Player controls a space ship, and flies straight forward. He must destroy enemies - the spacecraft has a gun that can be improved by power-ups and special weapons. Player can obtain helpers ("option" from Gradius). At the end of each level a boss awaits - every boss is heavily armed and difficult to destroy.

In Philosoma, you blast through 18 vertical scrolling deep space environments in search of the mysterious distress call, destroying enemies and obstacles in your path. Go up against a variety of vehicles including the "Hover Carrier," the "Makkon," and the "Missile Walker" as you clear your way with one of four main weapons such as the Vulcan, Laser, A-Break, or Ray-B. Each weapon can be upgraded up to three times when specific power-up icons are collected. A secondary weapon such as Buster grenades, MRMs, and SRMs are equipped at the beginning of a level or acquired through a power-up.

Dariusburst is a horizontal scrolling shooter developed by Pyramid and published by Taito. It forms part of the Darius series and it is released for the PlayStation Portable in December 24, 2009. Like previous Darius games, Dariusburst is an offbeat sci-fi shooter set in outer space with aquatic-themed (typically fish-shaped) robotic enemies. In keeping with tradition, the game also features branching paths instead of the linear progression found in most video games. There are a total of 11 zones in the game, with 5 stages per run. A related arcade game titled Dariusburst Another Chronicle was released on December 17, 2010, in a 32:9 dual widescreen cabinet. An update, Dariusburst Another Chronicle EX, was released in 2011. A revised port of the original game for iOS and Android, titled Dariusburst Second Prologue, was released on February 10, 2012, and October 24, 2015 in the US. An enhanced release titled Dariusburst Chronicle Saviours has been announced for PlayStation 4, PlayStation Vita, and Microsoft Windows. The game will be released in Japan by Kadokawa Games under their publishing division Chara-Ani, and was released internationally by Degica.

This futuristic shooter combines two distinct styles of gameplay into a multi-level romp through space. The colony planets of New Chicago have been overrun by gangs of Rrampon invaders, and a state-of-the-art space cruiser has been sent in to purge the infestation. It's up to the Star Breaker, and its android pilot, to destroy the enemy's airborne forces and dispatch the interlopers underground.

One or two players (in hot-seat or cooperative mode) control a spaceship equipped with a laser cannon which can be charged (by holding the shooting button down) for a stronger blast. Besides the main weapon, three special weapons are available: a wall of fire which wipes the screen up in a wave, a nova-like blast and a circle of spherical-green homing missiles.

It's the BEST IBM shooter yet! A fast paced slugfest, with a pulse-pounding sound track, and jaw-dropping VGA animation & cinematics. In the future as a mercenary flying the super-tech Raptor, you'll be sent on interplanetary missions to knock off top competitors of MegaCorp. Battle against hordes of relentless enemies. Spend the bounty you receive from their demise to expand your devastating arsenal, which can be upgraded with 14 hard core weapons! "Raptor has some of the hottest graphics ever seen in a shareware game, and blows away most commercial games, too! The graphics will amaze you and the sound will astound you. It's a super star!" -- Interactive Entertainment Raptor sets the new standard for PC shooters. This game will do for shooters what Wolfenstein did for 3D games. Incredibly smooth VGA graphics and animation are only half the story. The heart-pounding music in Raptor will leave you breathless, especially if you have a high-end sound card like the Roland or Wave Blaster. (Raptor supports the Midi music format, which provides very high quality music for PC games.) All other major sound cards are also supported! The addictive quality and replay value of this game is unreal. Discover secrets, find the bonuses, and battle the boss ships that appear at the end of EVERY WAVE! With each ship and ground target you destroy, you'll earn more cash to increase your ship's technology for the next wave. You'll be driven to kill and destroy--but then, it's in your blood.
