Its called mobile suit gundam: climax uc, and quite frankly, its not that good, ive had it for months now, maybe a year already, and it only gets good around f91 story ( like the last stuff) i only played through it to play with the f91, the rest was very mediocre.
Get Another Century's Episode 2 instead.

edit:
the intro of A.C.E. 2
