STONEHENGE RETURNS III

Stonehenge Return III is a Special Raid mission in Ace Combat Infinity that only appears after completion of an Online Co-Op Mission. It takes place at an upgraded Stonehenge Type-3. The premise involves the reactivation of the Stonehenge railgun system, requiring players to destroy it once more.

Objectives
Similar to the campaign mission, all players must neutralize the three jamming towers in the center of the facility. After doing so, they can destroy the railguns themselves. This mission is supposedly an upgraded version of Stonehenge Return and Stonehenge Return II, but details are not clear on what this upgrade involves.
