Retro Battleground.

Retro Battleground is a physics-based fighting game where players battle using only their fists. There is only one characters—just blocky figures that react to every punch with exaggerated knockback and ragdoll physics. The arenas are simple yet dynamic, with destructible platforms and hazards that make every fight unpredictable. With each punch, opponents go flying, bouncing off walls or falling into the void, making every moment chaotic and fun. The game embraces the nostalgic feel of early Roblox while focusing purely on movement, timing, and well-placed strikes to claim victory.
