Sunday vs Magazine is a crossover fighting game featuring dozens of characters from two of Japan's most popular shonen manga magazines: Shogakukan's Shonen Sunday and Kodansha's Shonen Magazine. It is a cel-shaded locked-view fighting game much like Street Fighter IV, and includes more than a dozen characters from each publisher's catalog, including contemporary series as well as older classic titles.
The game features three main modes. First, there is arcade mode, which pits the player against seven randomly-selected characters in order. Next is quest mode, which plays more like a scrolling beat-em-up and tasks the player with fulfilling various time-limited objectives like destroying targets or collecting keys, and which can be played solo or with up to three friend in wireless co-op. Last is the free battle mode, where the player can play a free battle against the computer or a friend via local wireless play.
The game system is relatively simple; characters have a limited set of moves, but they can be customized per character. Each character can also be upgraded using orbs earned in quest mode to buy new moves. In addition to regular moves, each character also has special super moves, which require use of a special bar which fills as the player lands blows. The player also unlocks assist characters as the game is played, which can be assigned to characters to give special assist moves.
There is also a database mode where the player can read introductions for each of the playable and assist characters. The full list of featured series are as follows.
