Cod mw3

[Psychopath]

Hello,

There is no point in asking, as you can download Warzone right now and test it for at least 48 hours to confirm whether you are banned or not.
As for BO6, seeing snippets from MW3 in the early days, I can tell you it's on the exact engine/platform.
All HWID bans will carry on to BO6 without a doubt.
You can also wait for the BO6 Open Beta around the COD NEXT event date and verify whether you are suspicious of being HWID banned.
