Fellwood casts forest harvesting as the engine of a growing lumber empire. The encampment begins with a handful of buildings and can expand into a sprawling operation, with each building bringing new attacks, upgrades, and faster ways to harvest. Its central appeal is the escalation: what starts as a modest camp develops into a forceful, increasingly busy industrial spectacle.
The game pairs that expansion with physical log piles, where thousands of logs can crash, stack, and spill as the operation scales. Collectors haul timber across the valley, converting each fallen tree into income for further growth. Progression also offers permanent Prestige upgrades and a broad set of level-up choices to customize each run, while active abilities, random events, and multiple projectile tiers add variation and firepower.
Fellwood is listed as single-player, so its lumber-yard growth and run customization are framed as an individual management-and-action experience rather than a shared multiplayer undertaking.
