M4Arena
SteamCreative Construction: Assemble your vehicle from a variety of parts, each with its own weight, shape, and special attributes. The sky's the limit—create anything from a sleek, agile rover to a hulking, unwieldy tank.

Customizable Joints: Fine-tune the elasticity and rigidity of your vehicle's joints. Will your contraption be a bouncy, spring-loaded menace or a sturdy, unyielding behemoth?

Physics-Based Mayhem: Every battle is governed by realistic physics. The way you design your vehicle—weight distribution, part placement, and joint configuration—determines how it performs on the battlefield.

Dynamic Battle Arenas: Fight in a variety of arenas, each with unique physical properties. Adjust your designs to cope with different gravity levels, obstacles, and environmental hazards.

Autonomous Combat: Once the battle begins, your vehicle is on its own. Watch as it maneuvers, attacks, and defends based on the structure and logic you’ve built into it. Community-Driven Development: We're all about listening to our players. Share your feedback, suggest new features, and help us shape the future of *M4Arena*. Our dev team is here to make this game as fun and chaotic as possible—with your help!
