Infectious Smile All Weapons Badge Guide and Item Locations

The Infectious Smile all weapons badge, officially titled Obtained All Weapons In One Life, requires holding eight specific weapons and tools simultaneously without dying. Players must collect the Bat, Bottle, Knife, Handgun, Shotgun, Hatchet, Ice Potion, and Invisibility Potion during a single survival run.

Required Items for the Badge

The Roblox badge description on the official Infectious Smile place page defines the exact checklist. Only eight specific items count toward completing the achievement:

• Bat
• Bottle
• Knife
• Handgun
• Shotgun
• Hatchet
• Ice Potion
• Invisibility Potion

Other gear found in the game does not count toward the requirement. Weapons such as the shovel, katana, spear, and packed ice are excluded. The developer description also excludes the tommy gun, so finding the safe in the raided hideout is unnecessary for this unlock. Every required weapon must sit in your hotbar inventory at the same time. If your character dies or turns into a smiler, inventory progress resets.

Where to Find Every Weapon and Potion

Items spawn across fixed locations and rotating stage rooms. Because the mountain changes maps periodically, completing the collection requires monitoring room rotations from safe positions.

Spawn Room Items

The lobby area provides two starting items immediately upon spawning:

• Bat: Picked up by interacting with the friendly NPC Rob behind the counter at spawn. It can also be retrieved from the bat box at spawn or inside The Fortress.
• Bottle: Obtained directly from Rob at spawn. This glass weapon cannot be found inside stage rooms and must be picked up from the counter.

Stage Weapons

Four weapons require entering active mountain stages:

• Knife: Spawns in the Knife Room on top of five jumping pillars. You must jump across the platforms to reach the shelf, step near the glowing purple brick, and click the embedded knife.
• Handgun: Found inside the Gun Factory or Steam Room stage. It provides 25 rounds of ammunition upon pickup.
• Shotgun: Located in the Laser Hall or the Cave Obby. In the Laser Hall, cross to the left doorway, climb the ladder across the hall, and drop into the hole leading to the wall mount. In the Cave Obby, navigate left across stone platforms when lava recedes.
• Hatchet: Placed at the end of the Forest Room obstacle course, inside the first-floor kitchen of The Cabin, or at the start of the conveyor belt in the Plank Factory.

Potions

Two specific consumables round out the inventory requirement:

• Ice Potion: Spawns exclusively in the Freezer room and the Chiller. It rests along the walkway to the left side of the entrance. Only one potion spawns per cycle.
• Invisibility Potion: Located in The Cabin stage. Head into the first-floor bedroom and locate the item sitting directly next to the bed.

Survival Strategy and Grab Escapes

Gathering all items requires staying alive through multiple room transitions. Smilers pursue humans aggressively, and touching white infecting lights or falling into stage hazards terminates the attempt.

A practical rhythm involves grabbing the bat and bottle from Rob, heading into an active stage to collect one target weapon, and quickly retreating to the spawn barrier or The Fortress. Orange depressing light barriers protect humans because smilers die instantly upon touching them.

Carrying a knife serves as primary protection against grabs. If a smiler catches you, clicking the knife breaks the hold at the cost of 3 durability points, allowing up to four escapes on a fresh 10-durability blade. The handgun and shotgun also provide fire support to knock back enemies or interrupt grab animations.

If an accidental grab or light hazard causes infection, do not reset immediately. When the swamp of sadness stage appears after a mountain collapse, standing in the rising tears will cure the smiler transformation, restoring your human character and saving your collected inventory.

Weapon Acquisition Options

Planning how to secure dangerous items reduces the chance of losing a run deep into the rotation.

Private server owners have access to server commands that simplify earning badges. Chatting :choosemap allows direct summoning of difficult stages such as the Freezer or The Cabin, eliminating the wait for public server cycles.
