Every Extend Extra is a puzzle-shooter game for the PlayStation Portable, developed by Kanta Matsuhisa. Players control a ship that can only self-detonate to eliminate enemies within its blast radius. The game features timed stages where players create chain reactions by triggering explosions among enemies, enhancing gameplay dynamics and strategy. The title expands on the concepts of its freeware predecessor, Every Extend.
In Every Extend, players control a ship with the only ability to detonate itself. Stages begin with a set time limit and enemies appearing on screen in randomized patterns. When the player detonates their ship and an enemy is caught in its blast radius, the enemy will explode and have its own blast radius that other enemies can get caught in, causing a chain reaction.
Every Extend Extra is a redevelopment of the popular freeware game Every Extend, which was a personal project by Kanta Matsuhisa under her `Omega` pseudonym.
