Wheatley on successful sapping

The Ap-Sap is a promotional building weapon for the Spy. He is based on Wheatley from the video game Portal 2; a flattened core with a glowing blue eye, with voice lines which are activated upon certain circumstances, such as when deployed or destroyed, and eyelids that move as he talks and widen when in range of a sappable building.

This weapon functions identically to the Sapper.

This item is awarded in Genuine quality to players who open a What's in the Portal 2 Soundtrack Box?, which was included via promo code with the Portal 2: Songs to Test By CD.
