Infectious Smile, by laughablehaha, puts up to 35 players on a mountain of rotating stages. Humans try to stay uninfected and reach the fortress before the disaster. Smilers try to grab humans or drag them into white Infecting Light.
Two teams
Humans start at the lobby. The NPC Rob, behind the counter, hands out a Bat and a glass Bottle. Smilers wear the Winning Smile face, turn their heads toward the nearest living human, and move faster than a human can run. A grab with empty hands drains a human. Touching white Infecting Light also converts a human. Orange Depressing Light kills Smilers and lets humans walk through.
When a Smiler dies, that player returns to spawn as a human unless something infects them again. In the main mode, Swamp of Sadness water can cure a Smiler without spending a life. Elimination mode does not use that cure.
Controls that matter
- Move with WASD and aim with the mouse. Shift Lock makes jumps and grabs easier to line up.
- Left click swings a human weapon. As a Smiler with empty hands, left click grabs.
- F interacts with chests, racks, buttons, and NPCs.
- You cannot reset out of a grab. The Knife and Handgun can still be used while grabbed. A Shotgun blast or a Hatchet throw can also break some holds. Teammates can hit the Smiler who is holding you.
The five-minute mountain
A seismic gauge fills for about five minutes, then a disaster hits: earthquake, flood, lava, or blizzard are the usual forms. Stand in spawn, on the side street, or inside the fortress when it triggers. After the collapse, the field rebuilds into two to four stages between camp and the fortress. Double-length stages such as Desolate Shelter, Old Labway, or Refrigerator Hallway take two slots, so fewer rooms appear.
The fortress gate is a shield controlled from inside. Humans who hold it stay safe during the disaster. If Smilers hold the fortress long enough, the orange forcefield drops and the building becomes a Smile base.
What to do first
- Take the Bat and Bottle from Rob. Do not ask for a second copy until the one you hold breaks.
- Walk the stages, skip white camera beams, and use orange light as a wall against Smilers.
- If you are grabbed, use a Knife, fire a Handgun, or call a teammate. Details are in the grab-escape guide.
- Spend Smile Coins on a Katana when you want speed, or a Spear when you want reach. The shop prices and level math are in the coins guide.
- Learn one key route before you hunt the Tommy Gun or the Giant Potion.
The Halloween listing on the Roblox page adds Voidtorn Takeover, the Pumpkinroom boss, a Halloween crate, a Spooky Bundle, two emotes, and eight more infection faces on the paid face pass. Read the event page before you assume an older map route is unchanged.
