Another server with a similar script?

At one point in time there was a server called “Paradox”. It was made in 2007, running CS_Desert.

The point of the script was running around killing zombies, getting money as you did so and being able to buy guns, ammo boxes, jet packs and such. Sort of like Dark RP but without using the script other than as a base. You built bases and just screwed around.

So I ask, is there any non round based Garry’s Mod servers that follows similar characteristics to this? I’m unsure if this is the correct place to ask.
