"Shoot at people whose army-navy-store cargo pants are a different color than yours" is a learned behavior by now, so we didn't think it would inconvenience you too much if we tracked down eighteen more color-coordinated psychopaths and put them on the payroll. Global Radio Network (GRN) and Yard Logistics Workers, Inc. (YLW) play a part in all the broadcast towers and freight yards you've been fighting over, respectively, but they've also got shady corporate interests that they're willing to hire mercenaries to protect. You're not so different after all!
Four-Team, also known as "4team", is a game mode introduced in the Death & Taxes update; as the name suggests the game mode features typical symmetrical gameplay, but players are now split between four teams instead of the usual two. These two new teams added are the GRN(Global Radio Network) and YLW(Yard Logistics Workers, Inc) team. Since teams will naturally be smaller in size, teamwork is encouraged and sticking together is advised.
The mechanics of a map having three or more teams first appeared in TFC, though in the base game only the Hunted map (which eventually evolved into VIP) utilized this mechanic. The Civilian was on Blue, Red was comprised of his bodyguards, and Yellow was the assassins.
