Brainwave Trials is a single player game set in the 22nd century. The player takes control of a volunteer for the Garnet Research And Development Sector in their technological development trials. The research facility imbibes the volunteer with enhanced physical abilities and dimensional manipulation abilities in order to progress through the test chambers of the facility.

The player will need to think "outside of the box" to overcome the challenges and trials that await them, gaining access to all new abilities within each chamber. By using a combination of their innate physical ability, enhanced parkour traversal, and dimensional manipulation, players will be able to solve the puzzles that await them.

As the player progresses, reality destabilizes around them, causing them to wonder what harm the advance of science might incur on reality.
