Gas Mask
BO2 Build Guide

Build an original flat gas mask with mint lenses, a centered snout, and paired cream filter cores.

Gas Mask BO2 emblem built with 13 native-shape layers
13native-shape layers

Build strategy

Plan this emblem before placing shapes.

Set the warm field and nested mask circles, then lock the paired lens stacks before completing the bridge, snout, and two filters.

Alignment reference

Keep the defining geometry stable.

Treat the bridge as the vertical ruler: both lenses and both filters should sit the same distance from it.

LAYER 1

Sand background

Begin with sand background using Square Full. Place the #E8BE67 shape in the middle center to establish the supporting silhouette. Keep later shapes inside or deliberately overlapping this first boundary.

Placement reference

Center at approximately 50% from the left and 50% from the top, using the canvas center lines as reference.

Use about 322% horizontal scale and 322% vertical scale relative to the simulator primitive.

What makes this build different

Built with documented BO2 Tools shapes.

Gas Mask uses Square Full, Full Circle, Rectangle Medium. Every visible part is a transformed instance of one of those primitives; no imported image, text, or custom polygon is hidden in the result.

Final review

Check the playercard-sized result.

  • The two mint lenses stay level and unobstructed.
  • The snout sits between the filters rather than over them.
  • All 13 layers use only Square Full, Full Circle, Rectangle Medium.
  • The design contains no imported image, text layer, hidden custom path, or direct game-import claim.

Manual reconstruction, not a game import.

This companion saves progress in the browser and shows one native-shape layer at a time, so you can follow the build at your own pace. It never connects to a game account.
