AC2

AC2 is an abbreviation that can refer to several different topics, depending on the context. In popular culture, it most commonly denotes two video games: Assassin's Creed II and Ace Combat 2.

Assassin's Creed II, released in 2009, is an action-adventure game developed by Ubisoft Montreal and published by Ubisoft. It is the direct sequel to the original Assassin's Creed and expands the series with an open-world depiction of Renaissance Italy. Players control Ezio Auditore da Firenze as he travels across cities such as Florence, Venice, and Rome, combining parkour-style traversal, stealth, and combat. The game introduced expanded character progression, a larger map, and a more interactive storyline, contributing to the franchise's ongoing success.

Ace Combat 2, released in 1999 for the PlayStation, is a flight simulation game developed by Project Aces and published by Namco (Namco Bandai). It is part of the Ace Combat series and is known for its arcade-style air combat, contemporary aircraft, and missions that emphasize dogfighting and precision bombing. The title helped establish the series’ blend of accessible flight gameplay with cinematic presentation and mission-based progression.

Beyond entertainment, AC2 can also appear as a model or revision code in technical documentation, product catalogs, or software releases. In such cases, the meaning is highly domain-specific and must be inferred from the surrounding context. In general, AC2 most often points to one of the two video games listed above.
