Obtaining the Giant Potion
Transforming into a giant is tied to consuming the Giant Potion, one of several specialized potions hidden throughout the game. Drinking this bottle triggers an earthquake effect across the server accompanied by tense music, expanding the player into a Giant Smile.
Acquiring the item involves solving room-specific puzzles across randomly selected stages. Most locations store the bottle behind heavy steel doors or cracked walls, requiring players to transport bombs or keys before the five-minute disaster timer collapses the mountain.
| Map Option | Best Scenario | Requirements |
|---|---|---|
| Lockers | Running a stage with key cabinets | Red key to collect the green key, followed by green key door access |
| Headcam | Accessing an active bomb spawn | Bomb detonation on the cracked wall and a green key for the interior door |
| Slime Room | Team pushes explosives across open terrain | Bomb spawned by holding E for 3 seconds, clearing the wall, and using a green key |
Stage Locations for the Giant Potion
The Giant Potion appears on specific stages that spawn during the standard five-minute map rotation. Because public servers cycle through four randomly placed zones, players must identify which stages hold the necessary items.
Lockers
Lockers features three floors lined with storage units. Tommy guns, green keys, and the Giant Potion spawn across the second and third levels. Players holding a red key can access a locked side room to claim a green key. Taking that green key to the designated vault door opens the chamber holding the Giant Potion. Because other players can take the bottle once the door opens, unlocking it without drawing attention prevents rivals from snatching the item.
Headcam
Headcam contains a glass floor suspended over wandering infected entities. At the center of the area sits a damaged wall structure. Detonating a bomb against the cracked section reveals an inner door. Inserting a green key opens this doorway, granting access to both a Tommy Gun and the Giant Potion. The bottle carries an in-game label warning against drinking in narrow areas, as expanding in tight spaces can trap the character inside geometry.
Slime Room
Slime Room contains divided platforms patrolled by splitting slimes. To the left side of the map sits a reinforced barrier. Holding the E key for three seconds spawns a bomb. Pushing this bomb directly into the cracked wall clears the obstruction, revealing a green lock. Using a green key opens the door to retrieve the Giant Potion.
Alternative Stage Spawns
Chained Office features a suspended metal plate operated by a lever. Raising or lowering the plate with the lever can reveal keys, weapons, and the Giant Potion. Green House 01 also places the potion next to an infected gate, accessible if players bring an explosive from another zone such as Safelab.
Giant Smile Stats and Abilities
Drinking the Giant Potion increases character scale and grants three times the health of a regular Smile. Normal Smiles possess 110 health, giving the giant a baseline pool of 330 health. If server conditions trigger the Endangered state, the giant gains an extra 100 health.
Ground Stomp and Crowd Control
Giants possess a stomp ability that strikes the ground, dealing 50 damage to nearby humans and applying an 8-second stun. Affected humans can stand back up after three seconds, but the wide area of effect disrupts defensive formations around doors and corridors.
Shoulder Riding and Health Regeneration
Giants can crouch down to allow standard Smiles to climb onto their shoulders. Smiles riding on a giant's back accelerate the giant's health recovery rate. The giant also has the option to toss mounted Smiles forward into human groups.
Grab Mechanics
When a Giant Smile grabs an uninfected survivor, standard defensive counterattacks fail. Humans cannot break free from a giant's grab using basic knives or swords. Breaking the hold requires specialized equipment, specifically a hatchet or a shotgun.
Hazards and Counters Against Giants
While giants possess superior health, their expanded hitboxes leave them vulnerable to multiple environmental hazards and targeted human attacks.
- Firearms deal heavy damage when hitting the oversized head model, as headshots multiply bullet damage by 1.5 to 2 times.
- Entering the water in swamp of sadness kills a Giant Smile immediately upon contact.
- Orange barriers in the survivor safe zone deal continuous damage to giants rather than causing instant death.
- Entering the narrow safe zone during an earthquake can bounce a giant off the mountain into the void.
- The giant spider inside the Spidercave event map eliminates any giant in a single hit.
- An elimination bug causes the giant to die instantly if an allied Smile riding on the giant's shoulders gets shot and killed.
