Three more stages down in my quest for self-flagellation!
45: Looks more threatening than it is. Tons of Mobile Suit squads with shields and the Garuda, the Frost Brothers and a crapton of Psyco and Destroy Gundams beyond them...but the only reinforcement is a gimped version of Big Duo Inferno. Just wade in and take care of business. Didn't even need Seven Swell, although I had to let one of the Frosts get away.
46: One reset - this is a fake-out stage and it got me good. It's got a very similar arrangement to 45, with a bunch of Gundam enemies and Psyco Gundams and battleships waiting behind them. Plus there's a time limit of four turns for the skill point, so with no upgrades the natural strategy is to get to those capital ships ASAP and start wearing them down, killing what grunts you can for Will while the rest get left for a cleanup MAP. Except that when you kill enough squads, everything retreats and a fresh set of Turn A enemies show up instead, including Turn X. And you have to kill them by turn 4 for the point. The first run I didn't even trigger them until turn 4 and had no chance in hell. The second time through I focused on wiping out grunts, got the Turn A goons to show up at the beginning of turn 3 and Seven Swell wiped the floor with them.
47: OMG REUBEN ISN'T NICE. The first half of this stage was a bitch. With no upgrades for me and 50% for them, Asakim's parallel Glory Star jerks got ~40% hit rates against Setsuko, and she got 4% against them. Thanks to 11/11 B I had 10 SP Inspire and Focus to make that more fair, but I still had two resets where they killed me on 10-20% chances. Lovely. But then I finally triumphed over the RNG, got the Balgora Glory's final upgrade, and went on to steamroll the second half of the level. It looked challenging when I thought I had to kill all three 60K-HP Chimeras, but then it turned out I only needed one, so I got the skill point with a turn to spare, and a Hyper Jammer from Xine's corpse.
Now on to the ZEUTH route! I've been looking forward to this.
