Ultrabox — About this game
The first Ultra Box is organized as a collection to browse rather than a single campaign to finish. Its menu leads into short games, stories, and miscellaneous features, each with its own purpose and pace. A useful first visit is to inspect the available entries and try one playable section before moving to another. Read the individual screen prompts because the controls used by a short game need not match the commands used to advance a story. Returning to the magazine menu is part of normal play. The variety comes from switching between activities while keeping their separate objectives clear.
