Strategic AI System

The Strategic AI System is a mission selection feature introduced in Ace Combat X: Skies of Deception. It allows the player to freely select any of the available missions instead of playing them in a sequential order.

Description
The Strategic AI System is available after completing Prelude, where the player is granted access to 3 separate missions. Choosing to play certain missions will affect subsequent missions (e.g. Playing Last Line of Defense and Rolling Thunder instead of The Midnight Sun grants access to the latter mission's alternate version, Ice Bound). Various gameplay factors are also affected as a result, such as a decreased time limit or radar interference.
