Dai-2-Ji Super Robot Taisen Z Saisei-hen (Super Robot Wars Z2: Saisei-hen), is an entry in Namco Bandai Games Super Robot Wars series, and the immediate sequel to Super Robot Wars Z2: Hakai-hen.
Despite its billing as a two-part game, Saisei-hen is entirely independent of Hakai-hen. Players will receive a starting bonus in Saisei-hen based on how many times they have completed Hakai-hen, along with an extra bonus for playing all of Hakai-hen's scenarios, but unlocked machines and pilots will not transfer.
Every series from Hakai-hen returns, with their sequels/second seasons debuting if applicable. Macross 7 makes its Z-series debut, with Dynamite 7 appearing for the first time in any SRW. The only completely new series, Tetsujin 28, is the 1980s incarnation of a robot series that predates even Mazinger.
