Cosmos X2

The primary action takes place on the top screen with all meters, map, character messages and choices at the bottom. Players control the Cosmos X2 to stop the alien invasion and travel to its source. The Cosmos X2 has a special Alignment system that allows it to change between two chosen alignments at will. The player has several meters to watch.

One meter is the Charge meter which automatically charges the X2's Shield ability; if the player is hit while this meter is charging or is fully charged, then the meter will reset. Another meter is the Level-Up meter which increases when the player reaches a certain number of points. The level-ups are randomized and range from weapon upgrades to missile upgrades. The ship has an energy meter that, when depleted when one alignment is equipped, will allow the player to use the other alignment until they complete the stage.

Taking place in a nameless alien planetary system, the humans of the system have been developing spacecraft capable of traveling the entire planetary system with ease. Two Cosmos class ships are created: the Cosmos X1 and X2. As the X1 goes on its maiden voyage through the planetary system, it disappears part-way through. Ensign Daverdy is assigned to pilot the Cosmos X2, the fighter variant of the Cosmos craft, and discover what happened to the X1. Upon reaching the point where Cosmos X1 disappeared, Daverdy comes across an alien invasion fleet that has captured the X1 and are on their way to his home world.
