[rossengeorgiev]

csgo/protobufs/gcsdk_gcmessages.proto

Line 170 in bf70a41

optional bytes game_data2 = 6;

I have done some reversing on the CS:GO GC packets, and it seems game_data is CMsgCStrike15Welcome and game_data2 is CMsgGCCStrike15_v2_MatchmakingGC2ClientHello.

This doesn't appear to be very useful anymore as it isn't any different from the one you receive in an event

Maybe this can be closed now?
