Shoot'Em Up games pit players against continuous waves of enemies with increasing difficulty and expect players to survive as long as they can. This research attempts to increase player satisfaction by adjusting the game difficulty and changing the way computer controlled opponents behave based on information gathered during gameplay. The system will apply online learning methods for the computer to ignore or exploit weaknesses and strengths of the player. Physiological feedback and gameplay statistics will be used to monitor current state of the player to adjust difficulty rules. Test subjects will play two different versions of the game, with and without dynamic difficulty adjustment, with no knowledge on which is which, before being asked about which one they prefer and why.
