TL;DR: Reply with recommended specs for running ~8 modified zombies servers
Hi there everyone, first time posting here!
Just have a quick question. Obviously I'm looking for the greatest bang for my buck. I want to host a handful of Zombies maps as well as a few modifications on each such as starting points, jug, etc. I have experience with ArmA 3 and Garry's Mod hosting but those all used web hosting and not VPS. VPS prices get really expensive fast and as I'll probably just keep it going out of pocket, I want the price to sit somewhere around 20 bucks a month. Keep in mind I'm Canadian so that's closer to 17 bucks American or something.
Please reply with specs as that's what I'm interested in. I can do the shopping, just need to know if I can get away with cheaper stuff (as this IS a game from 2012) or if I should be looking at other solutions.
Thanks for your time!
