Valve released an update for CS: GO, which introduced a new operation, “Broken Net,” and also reduced the cost of the SG 553 rifle.

According to legend, Left 4 Dead appeared just thanks to Counter-Strike. One small modification forbade the bots from using firearms and armed them only with knives. Doomed to rush into close combat, the bots looked very much like fast zombies from L4D. So the concept of the popular zombie shooter was born: machine guns and shotguns against claws and teeth. And after many years, CS repaid good for good.

Global Offensive has two maps modeled on L4D campaigns. On the first is a copy of the swamp village from Swamp Fever (L4D2). Observing players will also notice here a small yacht from The Sacrifice campaign. Another map directly quotes the episode of Death Toll (L4D): there is a lakeside house where fighters with the infected had to defend themselves before the arrival of the rescue ship.
