Visiting Hours is a sixteenth mission in Ace Combat 2. It is also the third mission of the Operation "A"LPHAVILLE branch.


Your operation this time is to destroy the enemy's geothermal plant. It is a difficult task because this base is completely covered by a dome shaped wall made of heavy resistant material. Bombing it directly will not be effective. We will first break into the base through a heat release vent, and then destroy their central cooling unit in order to stop the base from functioning. The heat release vent is closed at the moment, but our ground unit is scheduled to enter the base secretly and open it. We plan to open the vent at precisely 15:00 hours. The time window is very small in this operation, we can only keep the vent open for 90 seconds. A hit-and-breakaway operation with lightning speed must be employed.

Target: The enemy's geothermal plant base

Watch the clock, and don't waste a second!


There are two phases for the mission: Wait for three minutes until the clock on the top-right corner of the HUD hits 15:00, then fly inside the geothermal plant via an opening to destroy the sole target within ninety seconds. A red arrow shows up on the radar to guide the player into the geothermal plant when the countdown begins.

  • According to Asahi Higashiyama, who worked on Ace Combat 2 as a planner, Visiting Hours was supposed to take place in the daytime originally, but the developers later decided to change the setting to night, while forgetting that the voice recording for the mission briefing was already complete. As it was too late to re-record the voice or to make changes to the mission, the developers decided to tweak the Sun's graphics in order to make it look like the attack took place during an eclipse.[2]
