How does Altman Fighting Evolution 3 combine to shine?

Leo and Astra can use the light of friendship, so can Gauss and justice.

But the combination of Gaussian and justice can only be used in dual mode.

Gauss or Justicia can't send it out alone, but the Leo brothers are combined.

Body light can be emitted alone. Here, the trick of Leo brothers, the combination of Otto brothers.

Body light must be obtained by Leo through ten points, and so must Gauss and justice.

Both of them have to go through ten strongholds once to get this trick.

In the double mode, only Leo and Astra, Gauss and justice break through.

Two people can emit combined light by pressing the same key at the same time, while others can't. Either choose

Two identical Altman, can send a slay at the same time.
