(adsbygoogle = window.adsbygoogle || []).push({}); So I know for a fact that this is possible on the pc steam Version.
Would like to get some people together that can help me with my research for this.
Heres a vid of 24 Clients ingame:


And heres is the pc source to it:

Server patches: You must login or register to view this content.
Clientside patches: You must login or register to view this content.
Various common patches: You must login or register to view this content.

Just reply to this tweet if you want to help my figure this out

Try the following dvars when in a pre-lobby using forcehost.
party_maxplayers "24"
party_minplayers "1"

no you have to edit structs and stuff to handle more clients as that is what the server and client side patch does therefore for this to work everyone would need a modded ps3 inorder to join a game with that many clients :p
