Strato's Sylph Asterism

Strato's Sylph Asterism is a 2D air-combat action shooter. You control a Sylph in combat, choosing weapons and three characters; your attack power and movement change with your choices.

Story

Aster, a rookie Sylph, is assigned to Muroc base. On her first mission, while patrolling the airspace near the base, she encounters a MARXII. Through the mission’s confusion and hardships, Aster meets and comes to trust Noah and Chaika, and develops alongside them. The three eventually form a stage act known as the Asterism Corps.

Combat

You can attack with guns, fight at close range, lock on to enemies and launch missiles, or evade. Shielded enemies cannot be hit by guns and must be defeated with melee attacks. Your remaining ammunition is displayed on screen, and you can reload when a magazine runs out.

Weapons and characters

You choose which weapons to use and which three characters to take into battle. These choices affect your attack power, movement and other aspects of combat, allowing for different approaches based on your strategy. You can also reload and retrieve items at the same time.
