Dodonpachi Sai-Dai-Ou-Jou is a home port of the popular arcade game. The game features three ship types - A, B, or C - each with its own unique characteristics and gameplay styles. Players can choose between these ship types and dress their character in various outfits to refine their gameplay.
Hyper mode returns from previous games, allowing players to power up their normal weapon for a limited time. This enables the player to easily clear the screen of enemies and rack up high combos. The hyper meter is earned by collecting point items and killing enemies with a laser. The higher the player's hyper laser when activated, the more power their hyper shot and the longer it lasts.
Aside from a direct port of the arcade game, the home port includes an exclusive 360 Mode where players take control of new element doll Saya and her ship, Type-Z. This mode has a unique life bar system that combines life, bombs, and special attacks into a single meter. Players can also use Saya's unique shot to fire both simultaneously for a deadly bullet barrage.
The home port also includes several more new features such as a training mode, challenge mode, novice difficulty mode, "1.5" mode, and shop mode. A training mode allows players to try out playing from any stage, while a challenge mode tests players' ability to perform core tasks in the game. The novice difficulty mode provides a challenge targeted at intermediate players. A new "1.5" mode provides a rebalanced version of the original arcade mode based on feedback from expert players.
The shop mode allows players to purchase unlocks using points earned from playing the other modes, including concept art, in-game wallpapers, and the ability to play as Saya in arcade mode.
