Use metallic tunnel paint, applied by another player
Complete the Yellow Tower route and open the tunnel network. Enter from the Blue Tower-side tunnel, follow the strong color landmarks to the hidden makeover room and have a teammate apply metallic paint to at least one visible body section. The painted player should receive Big Makeover.
Before you start
Unlock the Yellow Tower tunnel network first.
Bring a light and leave a hand or backpack slot free.
Bring a teammate to perform the painting action.
Step-by-step
1
Enter near the Blue Tower
Use the community-demonstrated tunnel entrance near the Blue Tower as a consistent starting landmark.
2
Follow color landmarks
Move through the green-marked and mixed-color passages, returning to the last clear color if the group separates.
3
Cross the multicolored route
Continue over the multicolored bridge and use the red zigzag stairs as the next landmark.
4
Find the metallic palette
Enter the hidden makeover room and choose a paint with a visible metallic sheen.
5
Paint the target player
A teammate applies the metallic finish to a body section; wait for the target account’s achievement notification.
Visual route
Match the landmark before you move
Authorized gameplay screenshots and route videos are paired with text so the guide still works without media.
Screenshots retain the original game text; videos retain their original audio. Use the captions and written checkpoints alongside them.

Still stuck?
If the finish looks flat, the group may be using ordinary paint rather than the hidden metallic palette.
If the achievement does not unlock, swap who applies the paint and target a clear body section.
If the tunnels are closed, return to the Yellow Tower route instead of looking for an exterior switch.
