Plummet's House of Flux is a video game developed by MicroIllusions in 1989 for the Amiga.

Plummet has invited the player character to come to his House of Flux for a test of skills involving four different missions.

The player flies a ship with a gun and shield to save six captive astronauts from each level, avoiding or destroying obstacles placed by Dr.

The player can rotate the ship either clockwise or counter-clockwise by moving the joystick either to the left or to the right, and can thrust the ship forward by pushing the joystick forward.

The player can fire the guns on the ship using the joystick button, and raise the shields with the space bar.
