Plusmaster - PlusMW3
All I can find is TechnoGod/Technomw3 but there are no servers and you can't even start a private match, if anyone could direct me to a wroking 2015 one it would be appreciated.
PlusMW3 is pretty good actually.
When I finish my server backend, I'm gonna re-write my hacks for PlusMW3/TeknoMW3 and the soon-to-be-released TeknoMW3 3.0
But anyways, you can update it by going on their site and downloading the client version 2.7.3.7.
