rabidavocado a lot of people say they port forwarded but they either don't know what it really is or do it wrong

Did you ever find the solution?? I got multiplayer to work but zombies is still giving me the same error

Im having the exact opposite problem, how did you get zombies to work???

nvm fixed it just gotta set your controls to default and you can change it

FaZe Flick thats fair enough lol. Especially considering ive seen posts from like a year back or so talking bout wanting custom map support yet no news about it.

Have a good rest of your day or night

The optimization is fine once shaders have time to build. I get 500 frames with a 5800x, a two generation old CPU at this point.

black sayed the crash with this exception address is usually caused by picking up the CZ75 Dual Wield on maps other than Moon and the WaW maps. Either avoid picking them up, or use the fix I made here: https://forum.plutonium.pw/topic/38340/release-zm-cz75-dual-wield-crash-fix-exception-address-0x00415914

It’s likely cause by a mod you installed.

Use a VPN. You can't play with other users on the same IP for T5 aka Bo1. There are free VPNs available if you can't afford a paid one.
