Demon Attack is an arcade action game with gameplay similar to Space Invaders. You control a laser cannon at the bottom of the screen, and need to destroy wave after wave of brightly colored demons. The demons bounce around the screen in bizarre patterns, and try to destroy your cannon with bombs or lasers. When you shoot a demon, it will be replaced with another or will split into two smaller demons depending on which wave you are playing. When the required number of demons for the current round is finally destroyed, you can move on to the next, more difficult round.

The celestial planet Conceyta orbits with its moon in a dust- and gas-covered solar system. Within lurks an evil unknown to man that bears a danger so much greater than any threat yet witnessed. A dark, mysterious power has manifested itself in the depths of the gas giant, absorbing life and technology, and assimilating all in its wake. Spacecraft, pilots, androids, and computers: Nothing is safe. No one can escape the virus that infects all life forms, turning once brave heroes and peaceful colonists alike into ravaging, chaotic forces, fighting each other and infecting more in the process. Soulless technology and hate-driven humanoids are all that's left of Earth's once-proud fleet. The galaxy as we know it is threatening to fall apart. War, death, and bedlam have taken hold of civilisation. Humankind is at the brink of extinction. Those who aren't yet infected--the resistance, a band of mercenaries, soldiers and civilians--are Earth's final hope, and they have one goal in common: To stop the deadly infection and destroy the core of all evil, hidden in the depths of Conceyta. Scouts have undertaken a merciless mission to bring detailed plans and data on the location of the power and its defence line in a last attempt to save humankind. So it has come to be that the last remaining pilot, a mercenary and bounty hunter, is the only chance of survival, ironically driven by the desire for wealth and fame. Left with little choice, the resistance has developed a star fighter capable of intercepting the evil force, equipped with a deadly weapon system and of utmost agility. With no time to lose, the 10th and final prototype of the ship is handed to the pilot. Its name: "Sldner-X". Should the pilot succeed, his name shall live on in the memories of man forever to come. And so the battle begins.

Under Defeat is a shoot 'em up arcade game by G.rev. It was released for the Sega Dreamcast in March 2006. The game takes place in an alternate reality based on World War II, and, in a controversial twist, players control German-speaking characters (under the banner of "the Empire"), fighting against enemies ("the Union") that speak English and possess weapons patterned after those of both real-life Allied and Axis powers (for example, naval units in Level 2 bear heavy resemblance toward the Imperial Japanese warships). The game was released very late in the life of the Dreamcast, but sold much better than expected, probably because there were no other home ports planned in the foreseeable future. Players assume control of a helicopter, which can be rotated like a more limited version of the mechanism in Zero Gunner 2. Gameplay is largely very traditional, and bears a strong resemblance to some older Toaplan games, especially Twin Cobra. It uses 3D graphics, and a slightly angled perspective to give the game more depth than most other titles in the genre. On October 27, 2011, G.rev announced a remake titled Under Defeat HD to be released for the PlayStation 3 and Xbox 360.[1] The game is released by Rising Star Games on February 23, 2012 in Japan, November 9, 2012 in the UK and set to be released on November 28, 2012 in North America for PlayStation 3 only and January 25, 2013 in Europe. The Xbox 360 version for North America was released on August 26, 2014 as a downloadable game-only under Games on Demand. An upgraded version of Under Defeat HD (PS3, Xbox 360) was made on Sega Ring Edge 2 arcade System, named Under Defeat HD+. Now that version is coming to arcades with some improvements via Sega’s ALL.NET. Among the enhancements this will have is a horizontal orientation mode, more detail in the battlefield and a “New Order” mode where apparently you can choose from different types of aircraft.
