Sine Mora EX is an action-packed shoot 'em up game developed by THQ Nordic, available on PlayStation 4. The game has a unique setting described as "style-inspired dieselpunk" and features two different plots that develop at different points in time.

The first plot revolves around a father who seeks revenge against the Empire for executing his son, a bomber pilot, who refused to drop a nuclear bomb during the Enkies attack. The second story is about the last survivors of the Enkie race, who also want to take revenge on the Empire for destroying them.

The game is set on the planet Seol, which is very similar to Earth but has an unstable crust, causing frequent earthquakes. The game offers four difficulty levels: normal, challenging, hard, and insane. The player controls an aircraft with a primary weapon that can be upgraded and a secondary weapon that is more powerful but limited in use. The game has four different modes: Story, Arcade, Score Attack, and Boss Training. Instead of health, the player's state is measured by time, which can be reduced or increased based on the actions of enemies.
