Finished Prime 2 last night and the end bosses were fantastic just like most bosses in the game! Really glad I gave this game a second chance! Was worried I had to restart the Ing emperor boss after I lost to Dark Samus since the closest save station was offline but was glad the game saves after the emperor's death. I need to stop dying before learning the weak points of Metroid bosses though
Anyway looking forward to playing Fusion or Zero Mission in the future! So far I've defeated the end boss in all Prime games and Super and all games were great!
