ONLINE ARENA
Connecting to matchmaking…
You play the AI while waiting. As soon as a second player arrives, both ships are automatically warped into the same arena.

Re-enter arena
Players are paired two by two. The winner automatically returns to the queue for the next challenger; the loser is eliminated until choosing to re-enter.

SYSTEMS Automatic web matchmaking pairs visitors two by two into a synchronized human arena; winners stay queued for the next duel. Smooth adaptive zoom keeps both ships visible. Finite square arena with symmetrical left/right and top/bottom boundaries. Six ship classes with distinct silhouettes, handling, armor, primary weapons, special abilities and missiles. Guided missiles with progressive homing, gravity, explosive payloads, class-specific EMP effects, continuous collision detection and automatic reloading. Shield divided into eight independent faces: the selected face concentrates the largest reserve and absorbs substantially more damage than the other sectors. Class-specific regenerating energy systems. Both ship trajectories are calculated as a coupled 8-state ODE system using Runge–Kutta 4 integration. Two orbiting gravity wells with capture zones and approximate Lagrange points. RK4 future-path prediction plus a perturbed chaos-ghost trajectory. Fuel-dependent mass, engine/weapon heat, radiative cooling and dynamic shields. Kinetic-energy collision damage, damaged modules, asymmetric torque and persistent debris. Near-body atmosphere with drag and heating. Crossing either gravity-well capture radius triggers orbital collapse and ends the duel. Asteroids use continuous collision detection (CCD), solid impacts and progressive weapon destruction: cracks, integrity loss, chipping and final fragmentation. Weapon kills can release collectible bonuses: repair, shield surge, reactor cell or weapon overdrive. Asteroids destroyed naturally by planet impacts, atmosphere or asteroid collisions also have a smaller salvage-drop chance. Original implementation inspired by the classic space-duel genre; no Star Control artwork or characters are reproduced.
Portfolio project: standalone Canvas 2D game-laboratory combining RK4 ODEs, binary gravity, thermal/energy systems, modular damage, class-specific tactical AI and procedural rendering without an external game engine.
