Rival Megagun is a competitive vertical shooter built around split-screen duels. You and an opponent face separate waves of enemies on divided screens, but here's the twist: chain enough kills and you transform into a massive boss ship that invades the other player's side, forcing them to dodge your attacks while managing their own threats. It's less about surviving bullet patterns and more about offense—building meter faster, timing your transformation, overwhelming the other screen. Matches turn into tug-of-war scrambles where both players are simultaneously attacker and defender. The arcade shmup framework stays intact (scrolling stages, power-ups, tight hitboxes), but the PVP angle flips the usual survival focus into aggressive meter management. Works for anyone wanting head-to-head shooters without learning combo systems or frame data.
