Updated information about the Ace Combat 8 application has appeared on SteamDB, mentioning two additional games at once. By analogy with the previous installment, the publisher is likely planning to add a special pre-order bonus — Ace Combat Zero for PlayStation 2. This game is considered the chronological beginning of the series and takes place in 1995.
In addition, the files mention Ace Combat Online — a separate project focused on large-scale online battles.
The list also includes Ace Combat Zero: The Belkan War, Ace Combat 8: Wings of Theve, and Ace Combat Online, which is what drew attention to the changes in the SteamDB database.
