Foregone is a 2D action-platformer that combines soulslike and looter-shooter elements, set in the visually stunning, war-torn city of Calagan. Players take on the role of the Arbiter, a genetically enhanced super-soldier tasked with combating the Harrow, a malevolent force that raises the dead to threaten the living. The gameplay is characterized by fast-paced combat where players utilize a variety of melee and ranged weapons, and the need to engage closely with enemies to replenish ammunition adds a layer of strategy to encounters.

The game features a rich loot system, allowing players to collect a wide array of weapons, armor, and accessories, which can be upgraded at the central Outpost. Permanent progression through a skill tree and the option to retrieve lost items upon death enhances the gameplay experience. While the hand-crafted levels offer hidden secrets and challenge missions, some critiques have noted that the narrative may feel somewhat derivative despite the solid core mechanics and beautiful pixel art.
