- "Set in a stormy mountain sawmill, this arena map has its cap point in a large structure atop a hill in the center of the map; beneath which lies a hidden underground spytech base; and above which, pouring down on everything we just mentioned, is rain—the first weather effect to appear in a Team Fortress 2 map. If that previous sentence wasn't long enough for you, replace the period with a comma and add this next part: players must ALSO watch out for the two deadly saw blades near the cap, which were left on when the previous occupants abandoned it for a less deadly, hilly, rain-swamped sawmill not built on a spybase."
- ―The Sniper vs Spy Update (Day 2)
Sawmill was introduced as an official Team Fortress 2 Arena mode map with the Sniper vs. Spy Update. The map has since received official Capture the Flag and King of the Hill configurations that were released with the Classless Update.
The goal is to eliminate the entire enemy team or capture the central capture point when it becomes available.
