What Is Infectious Smile?
Infectious Smile is a Roblox horror survival game developed by laughablehaha. Players spawn as uninfected humans who must scavenge weapons and evade infected smilers, or spread the contagion across match stages by grabbing survivors with empty hands to convert everyone into grinning hostiles before the round clock expires.
Matches send survivors through randomized obstacle courses leading toward a safe fortress at the mountain summit. Players must withstand environmental disasters like rising lava or collapsing rock formations every five minutes, manage melee tool durability, and use protective depressing light barriers to repel chasing attackers.
