The picture was made last year for the game's release, but re-used today to thank players for the support and since it's still the 10th anniversary of the franchise.
As usual, still recommend to get this excellent game, it's been regularly 50% off already on all platforms (it was the case on Steam this weekend, and I think still the case today on PS4 and Switch), and its DLC has been on sale for the first time this week.
Hopefully they managed to get a profit out of it despite the bad release date, and the franchise will get a fifth game...
