The Armored Core series is renowned in the mech action genre for its intense one-on-one battles and customization options. Armored Core 5 is a new entry that revolutionizes the series with more content than the previous games, a completely new atmosphere, and a robust offline mode. In addition, the online mode has been newly designed to focus on huge team-based battles on a global scale. Featuring mechs or "Armored Cores" that are smaller in scale than in previous games, Armored Core 5 centers more on tactics and effectively utilizing the geography of a level rather than just relying on attacks.
