So the basic premise of how this works is pretty simple. I can give you god mode / unlimited ammo / and 1hp zombies and you get to farm away.
Prices are as follows:
Solo - $20 an hour ---> After 4 hours its $15 an hour *Can pay extra to timescale*
Full lobby - $15 an hour per person ---> After 4 hours its $10 an hour *Can pay extra to timescale*
I'll give you 5 minutes in a lobby for free to show you its real.
