Battle Royal: Roblox Edition

Step into your arena. In Ultimate Sigma, you don’t just fight—you build the battlefield. Design wild arenas with traps, towers, and secret zones, then drop in for a fast-paced free-for-all where custom Roblox avatars throw down. Power-ups spawn, the map shrinks, and only the real ones survive. Squad up or go solo, flex your builds and your skills, and prove you’re the ultimate Sigma. Can you dominate the chaos… or get clapped trying?
