World Boss is a fast-paced first-person shooter set in an ongoing arena free-for-all for up to 14 players. Fight to climb the scoreboard and become the World Boss, then hold off the other players as they try to take your crown.
Earn levels during a match and choose upgrades to your perks, weapons, and equipment. These choices shape your build and can combine in unusual ways, from a jetpack-equipped sniper to a rifle that fires rockets when you reload. Losing all your lives resets you to Level 1.
The arena’s top player can work toward corrupting the server, giving the other players a target to stop. You can also party up with as many as three Steam friends and adapt your build by watching what your opponents use.
Players who enjoyed World Boss often praised its entertaining, fast-paced fights and the variety of builds created by its perks and weapon upgrades. Some also found wins satisfying when they managed to turn a close fight around. Others felt the matches could be unbalanced or repetitive, and many reviews lament the dwindling player base and server shutdown.
Join Lannan “LazarBeam” Eacott and Harley “Fresh” Fresh for a brand new blend of FPS gameplay, custom build progression and the .IO genre – WORLD BOSS.

In the WORLD BOSS Arena, the action never stops, and no two runs are ever the same. Level up and upgrade your perks, weapons and equipment in an intense 14-player free-for-all. Climb the in-game scoreboard, and if you can hold the top spot, the World Boss crown is yours, and a chance to Corrupt the entire server. Keep an eye on your Lives, though. Losing them all will take you straight back to Level 1!

Honed FPS mechanics and fast-paced movement reward quick-thinking and lightning reflexes. Utilise an arsenal of unique perks, weapons and equipment each time you level up, playing to your strengths and their synergies. Get an edge on your competition by reading their build and adapting. Become unstoppable.

Want to be a sniper with a jetpack? How about an invisible XP Gem thief? Or use an Assault Rifle that fires rockets when you reload? With millions of combinations of perks, equipment and weapons, every Level gives you a choice, every Life is important, and every run is different.

Jump in, jump out. WORLD BOSS has been created to make it easy to get right into the action, from clicking play, to getting into our always-on servers. The game only ends when a worthy World Boss can corrupt the entire server. Party up to play against three of your Steam Friends. Play a single run or go again and again and vie for the World Boss crown. The choice is yours.
