While the first "SuperNova" introduced e-Amusement in a limited fashion, the service is taken to its full advantage in "SuperNova 2", a practice that would be replicated in future games. E-Amusement players are given additional information and stats and could participate in limited-time events. The game has a vast amount of post-release content delivered through e-Amusement up to a year after release. Since the service continues to be unavailable outside of Asia, Konami compensated this by sending codes to arcade operators which can be entered to unlock in-game content.
