In 2002, Capcom announced five different GameCube-exclusive titles that were collectively known as the "Capcom Five". However, Product Number 03 is the only one of the five titles to remain exclusive to the GameCube. Of the other four titles, three of them (Viewtiful Joe (2003), Resident Evil 4 (2005), Killer7 (2005)) were ported over to the PlayStation 2. The fifth title, Dead Phoenix, was canceled.
By completing the game a second time on the same game save, players can see the Client and Vanessa talking about six months after Alraune has been destroyed. They discuss the possibility of future work, plus you can see them outside of an Aegis suit for once.
