This week’s Famitsu reveals the first 4 stages of SRWL. So far only small scans were found with some info. Update: additional info from a 2ch thread.
1 – The boys guided by the Iron
Koichi goes out to buy bread in place of Shinji, who isn’t doing well at school. However, he’s smashed by a falling mobile weapon. Meanwhile, Ichitaka reaches professor Graife’s house. However, after he sees 2 robots there, professor is kidnapped by a mysterious person. Ichitaka deploys in the Rushbird to save him.
This is the stage presented previously at TGS, featuring Rushbird and Dancouga Nova, against the Kato Organization (which includes Wu-fei). Linebarrels becomes neutral and Painkiller and Hind-kind also make an appearance.
2 – Special Training, Mach Drill!
To gain some help on finding professor Graife, Ichitaka joins the Nation Alliance’s special forces Lotus. And Lotus is now contacting the several Super Robots that exist to gain their support. Meanwhile, during a special training at Build Base, Kenji is attacked by Isama of the Great Empire Jama.
Stage 2′s page is cut, so I can’t make out much, aside from the appearances of Jeeg, Mazinger Z, Aphrodite A and Boss Borot.
3 – Woman who fights, woman who doesn’t fight, woman who can’t fight
The Dannar Base members agree to join Lotus. However, one of the main pilots Go can’t use his unit, and his partner Anna ran away. During her escape, Anna is captured alongside her friend Nagisa by alien invaders called Cthuluf. At such moment, a woman named Iczer-1 appears.
Such a long title to present the debut of Iczer-1 and Nagisa’s pairing, as well as Com-Battler V, Godannar and Neo-Okuser.
4 – The Flame Giant appears
At Earth’s inner world Darius, the Daiku Maryu and Darius forces are at combat. However, Daiya is thrown at the outside world alongside Gaiking. He’s able to request help from Lotus, but Darius attacks. Will Lotus make it on time?
The stage seems to feature white/fake Gaiking: Kaikink, as well as Dancouga Nova unleashing Dancouken.
It’s also rumored that, in exchange for the Partner System’s unit bonuses, there are no Enhance Parts in this game at all. Let’s wait for confirmation.
