Pavlov is currently on 40% off, so to encourage people to give vrfps a go we'll be playing PvE Pavlov Zombies on the 29th at 1900UTC. Plan is to play for under two hours so you can buy it, give it a go, and refund it if you don't like it.
At the moment we're thinking of running this map since a similar one was run last time and was fun:

There are other PvE maps available too so if PvP/ S&D isn't your thing there's more to try. If people enjoy we could try other maps like Kino Der Toten, Der Riese, Nuketown, or a few other MC Zombies maps.
