I literally don’t know what it means but in my halo 4 it has a one on it and says
" Big Team Infinity Slayer "
Is it supposed to say my fave game type or something ? Need serious answers.
CSR stands for competitive skill rank. In Halo 4 Big Team Infinity Slayer was the playlist you reached the highest rank in which is why it is featured. It doesn’t necessarily mean that it was your favorite game type.
