Chaos Field

Chaos Field is a 2004 vertically scrolling shooter arcade video game developed by MileStone. The game consists entirely of boss battles, featuring five stages with three bosses each. The player can choose to play as one of three characters, each with their own ship that has a unique primary weapon. The player can flip the environment at will between two parallel worlds. Chaos Field is the first game from MileStone, a company founded by former Compile employees looking to develop high quality shooters similar to those Compile was known for in the past. The game experienced a troubled development cycle due to a lack of organization and the number of employees involved.
