Goblin Problem is a co-op tower defense game with RPG and strategy elements set on PC. Players control a hero while managing fortress construction and nightly defenses against goblin invasions in the kingdom of Grace Kingdom.
Gameplay
The core loop alternates between daytime preparation and nighttime combat. During the day, players build and upgrade defenses, recruit troops, and strengthen their hero using gold earned from previous nights. At night, waves of goblins attack the stronghold, requiring active hero control alongside automated towers and units to survive. The hero fights directly on the frontlines, using class-specific abilities to damage enemies and support defenses. Progression involves earning gold each morning to refine builds, upgrade the fortress, towers, troops, and hero abilities across multiple runs.
Five classes define hero playstyles. The Warrior serves as a tank and DPS option with heavy-hitting capabilities. The Mage focuses on spell-weaving for area damage or control. The Priest provides supportive healing and buffs. The Archer delivers ranged attacks from a distance. The Rogue emphasizes swift, precise strikes. Each class allows direct combat control to influence battles in real time while towers and troops handle broader defense.
Seven specialized defense towers offer variety in countering goblin threats through mixing and matching. RPG progression systems let players adapt strategies with each attempt, improving hero abilities and fortress layouts based on prior performance. The experience supports both short sessions focused on a single night and extended playthroughs across multiple maps.
Game Modes
The game centers on a single-player or co-op campaign structure where players reclaim overrun lands map by map. Each of the eight distinct maps features unique terrain and layouts that influence building placement and combat tactics. Progression through a map ends with a boss encounter that challenges both the hero and established defenses.
Co-op elements allow shared fortress management and combat efforts during defense phases. The loop emphasizes replayability through repeated runs on the same maps, where players refine hero builds, tower combinations, and troop recruitment to handle increasing difficulty or experiment with different class choices.
Key Features and Progression
Eight unique maps span varied battlefields, each presenting strategic challenges tied to layout and enemy approaches. Eight epic bosses command invasion forces at the end of each map, testing integrated defenses and hero skills in prolonged fights. Hero progression includes ability upgrades and playstyle customization as gold accumulates over successful nights.
Direct combat integration sets the experience apart, with players actively engaging goblins rather than relying solely on passive towers. Gold rewards from surviving nights fund ongoing improvements to the stronghold, specialized towers, recruited troops, and personal hero enhancements. The combination of building, recruitment, and frontline action creates a balanced strategy loop suitable for varied session lengths.
Is It Worth Playing?
Goblin Problem suits players who enjoy blending tower defense mechanics with active RPG combat and co-op fortress building. The day-night cycle provides clear structure for planning and execution, while class variety and map differences encourage experimentation across runs. Those seeking streamlined sessions with progression depth will find the hero upgrades and defense customization rewarding. The game delivers a focused experience on PC without requiring long commitments per session, making it a solid choice for strategy and action fans who appreciate integrated hero control during defense phases.
