Nightbreak is a medium weight competitive hero-based fantasy card game that features a fixed turn count, a day/night resource system, spatial positioning mechanics, and push your luck mechanics.

Players choose three Heroes from their faction and enter a battle with a duration of two in-game days. During each player's turn, that player gains at least one Blessing Point from their Goddess. Blessing Points are resources used to activate Hero powers. These resources also allow Heroes to escape from the battle undetected, or allow Heroes to pray to their Goddess for further blessings on a future turn.

As the battle progresses, Heroes take damage and eventually become overwhelmed forcing them to temporarily retire from the battle. When a Hero becomes overwhelmed, a new Hero from that player's Hero deck arrives to the battle. The player who overwhelms an opposing Hero gains favor from their Goddess. At the end of the two-day battle, the player that earned the most favor from their Goddess is the winner!
