Yes, you can indeed play Warzone 3 for free. The new rendition remains free to play across all platforms, be it on PC or console. As mentioned, Warzone 3 will carry forward the entirety of the base game from Warzone 2 but will have new implementations that have been promised with the Modern Warfare 3 integration.

Cash could be found by looting buildings and killing players that had cash on them. At launch, Warzone only offered Trios, a squad capacity of three players; Solos, Duos and Quads were eventually added to the game via post-launch updates. Upon release, Warzone received generally favorable reviews from critics.
