Does experience count when playing with bots, or only with Steam/Valve players?

I believe it works for both. I dont believe the zombie server had been updated to support the login system. However paintball i believe had bots it worked with. Seriously very soon we will publish a closed beta for registered PVP World veterans to access our Sphere Fight game we've been developing and of course we will be adding experience for that and eventually virtual assets like skins you could buy with the currency youve earned
