Team Fortress 2: Bloodwater

One of many community created Mann versus Machine (MvM) maps hosted on the Potato server group that has new maps once in a while. Some other community servers also host these maps sometimes. These maps are loud, fun, and more difficult than the base Valve MvM maps.

Pickup groups tend to hold the front line a little too well so I don't get to see how the middle of the map plays, but it's better than getting pushed all the way back to the deploy point if the team is doing terribly.
