Celtreos

Celtreos is a space shooter in the style of games from decades past. You pilot a small ship, use powerful weapons and face waves of foes, power-ups and obstacles. One or two players can play.

Stages

The game has 13 stages, including a city, a space station and an ocean. Stages scroll horizontally and have more than one screen of vertical space. You can start from any stage, and each ends with a challenging boss. Wall layouts and enemy spawn patterns are partially randomized.

Ships and weapons

You can choose from 10 ships, select weapons and special abilities, and customize ship properties such as gun mount locations and top speed. In-game power-ups grant weapons, defenses and temporary powers such as Rapid Fire; power-down orbs cause temporary inconveniences such as Weapon Freeze.

Music and sound

Celtreos includes 30 songs, totaling over 45 minutes of music. You can also play your own music and set it to advance automatically for key game events.

Game settings

You can set the number of lives and how many times special abilities can be used, choose one of three graphics quality levels, and adjust how much of the display the game uses in full-screen mode.
