Weapon X

A two-player duel built on one idea: you and your opponent plan in secret, then the plans collide. Each round you load three moves into three slots; the slots resolve left to right, and an element chart (fire, water, volt and their kin) decides who lands and who absorbs.

Play a friend hot-seat on one screen, or take on Zeroth, the machine. Zeroth runs entirely in your browser: it searches every legal plan against the ways you might answer and picks the line that survives its worst case. No server, no difficulty slider, just a mind that has already seen the fight.
