ACE COMBAT 4 SOUNDTRACK SHATTERED SKIES SERIES
Mobius 1 takes part in a series of air raids to disable Erusea's "invincible" Aegir Fleet, halting Erusea's attempts to invade North Point by sea. Mobius 1 and ISAF repel Erusean bombers from destroying ISAF headquarters and enable ISAF troops to evacuate to North Point. The player controls the game's silent protagonist, an ISAF pilot known by the callsign Mobius 1, while interludes are narrated by a man from San Salvacion writing a letter to Mobius 1 after the war recalling his childhood memories of wartime. Erusea gains control of most of Usea's mainland. Erusea is opposed by the Independent State Allied Forces (ISAF), but ISAF is forced to retreat outside Stonehenge's range to the island of North Point. Stonehenge is repurposed as a long-range anti-air weapon. Erusea also captures an array of anti-asteroid railguns codenamed Stonehenge which was developed to destroy the asteroid's fragments. Just before the game starts, the Federal Republic of Erusea invades and occupies the neutral country of San Salvacion. The impact events cause over 500,000 deaths in the first two weeks as well as an international financial crisis and refugee crisis. Four years prior to the events of the game, a massive asteroid enters and breaks up in Earth's atmosphere. The game is set in the alternate universe of Strangereal where Earth has different landmasses and history. On easier settings the player can survive several missile hits, while on the hardest a single missile can destroy the player. Multiple difficulty levels can be selected which determines the number of enemies, the AI skill and damage thresholds for both players and enemies.
