Seven Suns of Orion is a bullet heaven game for PC that distinguishes itself from the genre's standard formula by incorporating semi-Newtonian physics and gravity-based combat. Players are tasked with defending against an invading drone army, with each level requiring survival against waves of enemies for a seven-minute duration before a final boss encounter.

Quick Facts

  • Platform: PC (via Steam)
  • Core Mechanic: Semi-Newtonian movement where ships maintain forward momentum when turning or accelerating.
  • Environmental Hazards: Moons and asteroids create gravity wells that can be used to trap or destroy swarms of drones.
  • Ship Variety: Multiple unlockable ships, including the Cruiser, Galleon, and Fighter, each with unique handling and weapon configurations.
  • Price: £4.59

Physics and Combat Mechanics

Unlike traditional bullet heaven titles, Seven Suns of Orion emphasizes momentum-based movement similar to Star Control. When players accelerate or turn, their ship maintains its previous trajectory, creating an arcing motion that players must manage while avoiding enemy swarms. This movement is complicated by the presence of planets and moons, which exert gravity on the player's ship and can be used to pull in and destroy pursuing drones.

Weaponry in the game includes railguns, homing missiles, short-range lasers, flak cannons, and point defense cannons. Because weapon ports are fixed to specific parts of a ship—such as the sides on the heavy Galleon or the front on the agile Fighter—the choice of vessel dictates how players must position themselves in relation to enemy hordes.

Progression and Unlocks

Players earn coins during missions to purchase permanent upgrades and new ships. While the starter Cruiser offers a balanced experience, unlocking additional ships provides access to different handling schemes and specialized combat roles. According to the game's store page, these are not merely stat-based changes but involve distinct control profiles that alter how players engage with the game's gravitational environment.
