What is Spacewar!?

Spacewar! is one of the earliest digital computer video games, featuring two players each piloting a starship in a gravity‑filled arena. The central star’s pull forces players to master maneuvering while trying to destroy the opponent. Originally created in 1962, it was later ported to a coin‑operated PDP‑11 as Galaxy Game in 1971, marking a milestone in arcade history.
