Is the Su-57 playable in Ace Combat 8?
The Su-57 has appeared as an aircraft in official footage, but its player unlock status has not been explicitly confirmed.
Confirmed explanation
An aircraft appearing as an enemy or cinematic asset is not enough to establish a selectable campaign or online aircraft. This site waits for an aircraft-tree entry, store entitlement or direct publisher statement before labeling it playable.
What is not confirmed yet
Its unlock route, special weapons, upgrade path and mode availability remain unannounced.
