FTRP wouldn't come back without a massive overhaul.
If anyone with access to the FTRP boards manages to find my fucking speech about what FTRP should be that got a tonne of approval, I'd be grateful.
If I remember, it was something about how barely any infected would still be alive a year after the outbreak, and how it'd primarily focus on passiveRP and wandering through the remnants of humanity with decaying corpses littering the streets, the primary enemies being say, the Russian military trying to control the infection with soldiers and carpet bombs, similar to that one level from L4D2 in The Parish where you have to hide in buildings to avoid the carpet bombings.
Obviously, any infected remaining would be at Titan levels of mutation, and would look like this
at the minimum.
There'd be less of a focus on loot, because it'd be clear from the start that it's rare. You wouldn't need too many admins since it's less actionRP, and you could probably do with a few players on the event team for the constant daily events they loved so much.
