About Radius Raid

Radius Raid is a stylish, intense browser-based space shooter that reimagines the genre within a circular arena. Instead of scrolling levels or a traditional rectangular battlefield, you defend a central core from waves of enemies that pour in from all directions simultaneously. Your ship orbits the core, and enemies approach from every angle — requiring constant rotation, quick targeting, and ruthless priority management to survive. Built as a submission for the js13kGames competition (where the entire game must fit within 13 kilobytes of JavaScript), Radius Raid is a technical marvel of compressed design. Every visual effect, enemy behavior, and audio cue was crafted under extreme code size constraints, yet the result is a fluid, polished shooter that punches well above its weight. The tight code forces elegant design decisions: clean geometry, minimal but effective particle effects, and AI patterns that are simple to implement but challenging to survive against. The game's circular arena mechanic changes shooter fundamentals in fascinating ways. In traditional shooters, threats come from in front or above; in Radius Raid, they come from all sides simultaneously. There's no safe direction — the defensive perimeter is 360 degrees. You must constantly scan the entire arena, prioritizing fast enemies over slow ones and protecting the weakest section of your perimeter at any given moment. Combos drive the scoring system: each consecutive enemy you destroy without a break increases your multiplier, and devastating combo chains against clustered enemy waves can multiply your score by 10x or more. Building and maintaining combos while managing a deteriorating perimeter is the game's central tension. Radius Raid features multiple difficulty waves that introduce new enemy types — some that move in formation, some that scatter on approach, some that spawn smaller sub-units on destruction. The escalating variety keeps the experience fresh across multiple sessions. This is a game for players who love old-school arcade shooters but want something that feels genuinely fresh. It's visually striking with its glowing vector aesthetic and requires genuine skill to master. Best played on desktop with mouse controls for precise aiming.
