Decal

Decals are rewards, similar to achievements, used to signify the number of StarCraft II games a player has won. They appear on and around buildings and on at least some units. Decals used with the protoss will have a circle around them, and be your color. Decals used by the zerg are displayed on the creep surrounding a hatchery.
