The mutation chamber

The mutation chamber was a zerg structure in the StarCraft beta. Its wireframe is identical to that of the defiler mound, though its in-game appearance is unique.[1][2]

An earlier version of the defiler mound's sprite was named "mutation pit,"[2][3] shortened to "muta pit" as a placeholder.[4] The two structures may have been related.

The greater spire used "muta chamber" as a placeholder name.[4]

The mutation chamber's sprite was designed by artist Maxx Marshall and provided the inspiration for the mineral field's sprite.[5]
