Activision has claimed that Call of Duty: Ghosts is the best-selling PS4 game "in retail sales" in North America.
In an announcement on Wednesday, the publisher said the game has topped "retail sales on the new platform", which launched November 15. CEO Eric Hirshberg goes on to say, more specifically, "Call of Duty: Ghosts is the No. 1 best-selling game on PS4 in North America at Best Buy, GameStop, Target and Walmart."
The firm held off releasing hard sales figures, and it's unclear if its claim of being the top-selling game in "retail sales" accounts for all retail across US or specifically just the aforementioned retailers.
It also doesn't account for digital sales via the US PlayStation Store, which has offered the full game - and most of the PS4's launch titles - since November 15. A digital version of CoD: Ghosts is also offered viaSony's cross-gen upgrade program to those who purchased a PS3 version of the game.
Activision also reports that the game is the "no. 1 pre-ordered Xbox One title in North America" at the same retailers, again not accounting for complete pre-orders across all outlets. The Xbox One version arrives alongside the console this Friday.
The company said earlier this month that retailers spent over $1 billion worldwide to secure Call of Duty: Ghosts stock for launch day. While Activision Blizzard CEO Bobby Kotick said it was "too early to assess" sell-through to consumers, he suggested the game's release came at a time "when the franchise has never been more popular".
