In addition to the original games, this package includes an artwork gallery, music player, special filters, and much more. Casual Scenario Mode and a Save-Assist feature are available for those who would like to enjoy the story at their own pace. Players can also try their hand at the new leaderboard-based Z Chaser Mode, an exclusive new mode created just for this set of games.
