"Welcome zombies... To your worst nightmare. Prepare to be spawn killed... A LOT."


A small, enclosed map. While the building can be fun to hole up in, you still have the surrounding frozen body of water to explore.

Just please don't block the ladders.

Background Story

Foxriver Prison serves as a solitary one. It's not Alcatraz by any means, housing individuals deemed not dangerous, but just unstable enough to not be safe to be released back into society.

Guards who worked here lived here. Their only entertainment was from the other prisoners, and besides the occasional quibble, it got boring.

When communication outside the island ceased, the guards felt uneasy. Their suspicions were only confirmed went their monthly drop of supplies didn't arrive. The zombies on the horizon didn't help either.

In a hurry and without the Prisoners, the guards left the island on the only boat they had. By the time the Prisoners got out of their cells, it was too late, the guards were gone and it started snowing...


Unsurprisingly, Foxriver Prison has only one location of interest: the prison. While the outside is relatively open, the tight corridors can easily overwhelm you unless you know what you are doing.

Inside the prison, there are some cells on the first floor, a cafeteria on the second, and roof access. Outside, there is a basketball court. There is also a small guard tower attached to a building that's not connected to the main building.

Surrounding the whole place is a frozen lake.


  • Don't block the ladders using a Hammer. It's not helpful.
    • Think long-term. If everything goes wrong, you need mobility.
    • If a player has done so, you can scale the wall with parkour.
    • If this is an issue, you can climb the outside with parkour.
  • As of v1.0.0a, Diggers can now use their Dig ability on this map.
  • Because of how small the map is, you can easily farm money and EXP from killing zombies since they spawn in tight areas.
  • The RPG is a great weapon for this map. This is an easy way to get high Killstreaks by firing from the roof or outside of the prison.
  • Be aware that two of the doors in the cell portion of the prison do not actually open.


  • In v0.9.2, this map got recoloured to the colours you see today.
  • When initially released, Foxriver Prison was originally called "Fox River State Penitentiary".
  • For Christmas Event 2016, this map got a makeover!
    • The size of this map technically increased as the frozen sea could now be walked on.
      • This was the only map to have gameplay changes. The other two just received makeovers.
  • The removed Barbed Wire Fence can be seen on top of the gates to Foxriver Prison.
  • Terrain water used to embrace this entire map.
    • The winter theme from Christmas 2016 may have been removed, but the weather remains unchanged.
    • This made Foxriver Prison one of the three maps where the Snowball can actually be used.
  • To prevent Hammer users blocking the only path to the main prison roof, v1.0.1 had another ladder installed.
