When a player collides with the body of an enemy unit, the player loses a shot power level, and a power up flies around the screen and disappears as soon as it reaches the edge. If a player is at the lowest level of shot, the player loses a bomb instead.
There are seven stages in each of the game's two loops. The first three stages are randomly chosen from possible four. In the second loop enemies fire denser bullet patterns moving at faster speeds. Stage 2-1 takes place at the only stage not available on the first loop, instead of the 1-1 counterpart. The remaining two stages are chosen at random, but does not include the replaced stage. After completing first loop with only one player, the player can choose one of two choices for a wish with a magic potion, with unique endings for each choice. If the first loop is completed with two players, a combination-specific ending is played.
The cutscenes between the battles with two players fighting cooperatively are frequently packed with hilarious dialogue and situations. This is often a recurring theme with Psikyo games, the Gunbird games being no exception. There are no cutscenes when playing second loop stages
