You almost had me.
Apropos of nothing, Wrench #100 just dropped. Some guy named DoomSwitch.
The Gunslinger: Metal glove, replaces pistol, wait, no, it replaces the wrench, dammit Valve stop editing the update page after it goes up, +25 max HP, 3 punch combo, last hit crits. Allows deployment of Combat Mini Sentries, which cost only 100 metal and build 4x faster with full health, but cannot be upgraded or repaired and deal half damage.
Also yet another payload map, Thunder Mountain.
Also achievement descriptions are up.
