Category:Kai2 (retrofit)

The Kai2 (or "改二" in kanji [pronounced "gǎi èr" in Mandarin Chinese] meaning "to reform twice") of certain mechs/aircrafts/tanks are even more powerful versions of their already powerful Kai1 predecessors, and to be able to "Kai2-ify" a Kai1 mech/aircraft/tank is by itself an even greater feat. They too, can also be seen on the Retrofit subsection through the Develop section, all previous viewing constraints appertaining.

Like the Kai1s, most Kai2s are usually of the SSS-class, and fewer with a lower class being able to be retrofitted once again.

The Kai2s only require two active steps this time, unlocking and retrofitting, with all current rules applying as when you "Kai1-ify." The only difference is that you only need the Kai1 predecessor in order to retrofit, as the requirement of needing a maxed-out mech is already fulfilled.

One thing to note is that the chances of the use of a specific retrofit material for unlocking certain Kai2s becomes higher. Some Kai2s require a specific retrofit material (also found in the completion of quests or in the Retrofit Cube) to be retrofitted, and they are currently (expand the list below!):

Again, like before, if the Kai2 mech is from a collaboration, the use of collaboration-specific battle data might be used as unlock and retrofit material in lieu of parts or shards of parts.

On average, Kai2s tend to cost just a tad bit more to unlock compared to their Kai1 predecessors. In some cases, the Kai2 mech may be the ultimate expression of all its predecessors. Like before, retrofitting takes time.

When all is said and done, the Kai2 will now have a new max-star cap of 11-stars. The 11th star will actually just be displayed as a red star where the first yellow star used to be, followed by nine yellow stars.

Whatever the case may be, a Kai2 mech is again WAY, WAY stronger than its predecessor. Most players would say they are also worth the grinding effort. Happy retrofitting, everyone!
