20XX and its sequel 30XX are rogue-lite action-jump-n-run platformers for Nintendo Switch that blend fast, precise Mega Man-style combat with procedurally generated levels. Players collect power-ups, upgrade permanent abilities, and can team up in local or online co-op. 30XX adds new characters, a deeper skill-fusion system, and expanded level variety while retaining the core fast-paced platforming and endless replayability.
