- ―The Demoman on the Cauldron Fire
The objective of Foundry is to control all five capture points. Each team starts with their second and final control points locked, leaving only the middle point available. There are two steam whistles at the center control point, one RED and one BLU. If BLU captures a control point, their steam whistle emits steam while playing a train-like tone, and vice versa. There are 12 map-specific achievements for Foundry. Upon unlocking 7 achievements, the player will earn the Full Head Of Steam, an all-class hat.
