Nightmare Busters is a run and gun action game that follows the story of two leprechaun brothers, Flynn and Floyd. An evil fiend named the Tyrant has hijacked and spoiled the dreams of small children, prompting the brothers to take action. With razor-sharp playing cards and magical attacks at their disposal, they must traverse the dream world and overcome the Tyrant's minions to face the monster himself.
Gameplay involves quick reflexes as players navigate through levels, shooting enemies and collecting power-ups to aid in their quest. The game can be played solo or with a friend, working together to take down hordes of monsters in cooperative mode.
