The change to free-to-play is pretty straightforward. The base game is now entirely free, giving players instant access to “all game modes, matchmaking, and a limited set of item drops and weapon cases.”
However, there’s also the option to spend $19.50 to attain “Prime” status, which drops you into a special matchmaking pool and makes you eligible for “Prime-exclusive souvenir items, item drops, and weapon cases.”
As for battle royale, Counter-Strike’s take on the mode to end all modes is of a smaller scale than genre behemoths like Fortnite and PUBG, with player counts clocking in at 16-18 depending on whether you queue up solo or in a squad of two or three.
Guns will behave the same as they do in other CS:GO modes, but you’ll have to scramble to find weapons and cash- which you can use to buy more weapons and have them delivered to your position by drones. You’ll also be able to earn money by completing special mini-missions like contracts and hostage rescues.
In addition, you’ll have access to a tablet that can be used to track deliveries and opponents’ positions. So basically, Valve has made a battle royale mode out of ordering from Amazon during the holiday season.
