Infectious Smile Face Options, Pass Unlocks, and Mechanics

Infectious Smile face mechanics center on the default Winning Smile, which replaces human avatars upon infection. Purchasing the Choose Infection Face pass grants custom options like Stitchface or Man Face, while touching swamp water reverts smilers back to humans with the Sad face.

Winning Smile Mechanics and Visual Behavior

Every human player who transforms into an infected smiler receives the Winning Smile face by default. The design originates from the free cosmetic face on the Roblox avatar shop. When a smiler drains a survivor's health through a grab or when a player steps onto white infecting light, the infection sequence triggers. The player's camera gains a dark vignette, a distinct jingle plays, and the screen displays the message that the player is finally happy.

Infection immediately alters the character model. Any cosmetic accessories worn on the player's face detach during the grab or transformation. To prevent humans from disguising themselves by wearing the Winning Smile on their base avatar, the game causes infected smilers' heads to turn toward the nearest living human. Smilers also receive a protest sign bearing the Winning Smile image upon turning.

When a smiler contracts the rare overseer or seeker mutation, the head expands into an oversized version. In addition, an easter egg tied to the spawn NPC Rob alters facial cosmetic behavior: an infected player whose avatar matches Rob's appearance exactly will attach the victim's face accessory upon infecting them.

Choose Infection Face Pass and Roster

Players can override the default Winning Smile by obtaining the Choose Infection Face game pass. The permanent pass sells on the game store for 225 Robux, while an alternate single-life rental exists in the spawn lobby for 12 Robux. A dedicated menu button on the main home screen opens the selection interface.

Selecting an option from the menu assigns that face to the player upon stepping onto an infection pad or turning via enemy grab. When an infected player with this pass infects a human victim, the victim also receives that specific face rather than the baseline Winning Smile.

The pass initially introduced 26 distinct face options:

• Award-Winning Smile
• Awkward Grin
• Braces
• Classic Male - Face
• Crazy Happy
• Friendly Cyclops
• Friendly Smile
• Golden Bling Braces
• Golden Shiny Teeth
• Hockey Face
• I <3 New Site Theme
• Look At My Nose
• Man Face
• Monster Smile
• Overjoyed Smile
• Pieface Jellyfreckles
• Smiling Girl
• Stitchface
• Super Happy Joy
• The Winning Smile
• Timmy McPwnage
• Too Much Candy
• Toothless
• Woman Face
• Xtreme Happy
• Zombie Face

Subsequent game updates expanded this roster by adding 8 new infection faces to the selection menu.

Selecting Faces for Tactical Advantage

Different face selections alter how opposing players react in matches. In elimination mode, smilers frequently use human-styled expressions such as Man Face, Woman Face, or Classic Male to blend into dimly lit corridors and confuse fleeing survivors armed with a bat.

Equipping Stitchface is another common tactic among players. Because Stitchface carries a negative reputation among Roblox communities, victims forced into wearing it frequently choose to reset their characters immediately. When an infected victim dies, the infecting player earns 5 Smile Coins, making rapid target resets a viable method for gathering coins quickly.

The Choose Infection Face pass ranks alongside the permanent knife from the VIP pass as one of the most prominent cosmetic purchases in the shop. Players evaluating premium options across the full list of gamepasses often choose between utility weapons and infection customization.

Swamp Curing and the Sad Face

The swamp of sadness stage features a unique face mechanic tied to the water basin. While regular smilers die upon touching orange depressing light shields, contacting the clean blue swamp water cures the smiler without causing death.

Touching the water removes the infection and restores the player to the human team along with any weapons collected before transformation. Upon curing, the character's facial expression switches to the Sad face, provided the avatar is not wearing an animated 3D head. Giant smilers do not receive this expression change, as contact with curing water destroys a giant instantly.
