Perihelion is a physics-based space combat roguelite that blends action, RPG, and adventure elements on PC. Players launch from a carrier into orbital missions where gravity dictates movement and strategy, building ship upgrades across runs while uncovering a narrative about a vanished sister ship. The experience supports both solo play and cooperative sessions with up to four pilots.
Gameplay
Core combat revolves around momentum, velocity inheritance on projectiles, and planetary gravitational pulls that curve trajectories and enable slingshot maneuvers. Pilots must time accelerations and positioning to gain speed or redirect attacks, turning apparent chaos into tactical advantages during high-speed engagements. Ship builds evolve through choices made after each sortie, such as boosting fire rates, modifying projectile paths, or applying effects like burn and EMP on hits. These stack during a single run to create varied performance profiles.
Persistent progression occurs via a skill tree accessed between missions on the carrier. Investments here enhance hull durability, offensive output, or resource management and carry over to future attempts. Failed runs still yield upgrades, supporting steady advancement regardless of outcome. Crew interactions add depth through conversations with officers and leads that influence trust levels and reveal additional story layers tied to the central mystery.
Game Modes
Single-player runs focus on independent orbital sorties where branching mission paths adapt based on performance and choices. Co-op extends this to groups of up to four, requiring coordination on slingshot paths and shared radar information while scaling enemy encounters to squad size. Both formats emphasize repeated attempts with accumulating upgrades, allowing players to refine strategies over multiple sessions without resetting core progress.
Ship Building and Progression
Run-specific upgrades alter weapon behavior and introduce status effects that interact in complex ways, encouraging experimentation with combinations that suit different combat styles. The carrier-based skill tree provides long-term growth in survivability and firepower, making each new attempt more capable than the last. Resource economy improvements help sustain longer missions as builds mature.
Story and Exploration
Narrative elements unfold gradually through recovered data and encounters during missions. Relationships built with crew members unlock alternate threads that alter how the disappearance of the sister ship is revealed. This structure rewards multiple runs with new context and details that expand the overall mystery.
Is It Worth Playing?
Perihelion targets players who enjoy roguelite structures combined with physics-driven combat and cooperative space action. The emphasis on gravity as a core mechanic and persistent upgrades creates a loop where each attempt builds directly on prior progress. With a 2027 release date and no user reviews available yet, the game remains in development, but the described systems suggest strong appeal for those seeking challenging orbital encounters and narrative discovery over repeated playthroughs. Availability on PC supports both solo and small-group sessions without additional requirements.
