Odaclick revealed on October 5 how Streets of Survival combines exploration, supplies, and arcade brawling. Rick, Daryl, and Michonne have distinct weapons, animations, and their own skill trees.
The developers consider hordes of walkers and Savior fighters as different threats: the former are overwhelming in numbers, the latter can block and attack from a distance. Therefore, position and ammunition consumption are more important than the same approach to each enemy. After the finale, levels can be completed with different characters, including the unlockable Negan. The game is already available on PC and Xbox Series X|S; Play Anywhere and shared saves are confirmed in the official post. This is information about the finished game, and not an announcement of the October 5 date: the store indicates the release on September 18.
