SD Gundam Generation World (PSP) - Custom Challenge [22] B10 燃える砂塵 

Another helpless ship defense mission. We just had that 2 missions ago in B08! Geez.
That aside, this is a pretty fun stage, showing off both the original fight between Amuro and Ramba Ral, as well as the SEED take on this between Kira and Bartfeld. The Challenge Mission is to take down at least 10 BuCUEs before taking down Bartfeld with Kira. Since I was pretty close to evolving both 00 and Ex-S, I did a few runs of A01 to end this. Now I have no reason to grind for the main game ever, outside of being stuck. I did a ton of grinding the first time I played this, so it's quite interesting to see that I can actually grab all the top tier units I wanted by the end of the B series of stages.
The part unlock for B10 is スーパーナノスキン装甲 (Super Nanoskin Armour) which recovers 10% of your maximum HP at the start of every turn. The other unlocks going through A01 were:
ビクトルエンジン (Victor? Engine), +5 to unit Attack and Defence
ララァの思念 (The Will of Lala), recovers 10% of your maximum EN at the start of every turn
ビーム・ジェネレーターβ (Beam Generator Beta), increases the attack power of BEAM type weapons by 20%
