Dai-2-ji Super Robot Taisen Z: Saisei-hen, yet another game in Namco Bandai's Super Robot Wars series, is the immediate sequel to Super Robot Wars Z2: Hakai-hen.

Despite its billing as a two-part game, Saise-hen is entirely independent of Hakai-hen. Players will receive a starting bonus in Saise-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.
