Ok, any hints on how to beat the battle at the northwest base at night (against the many "??" attackers?) The difficulty level dramatically increases and can get the first one with Hyato & full group (before they escape to the second location and Hayato fights alone) but when going to the second location the chars left (Rex Aika, Tomi) just can't handle it with another "??" of such a huge increase in power. If you lose it's game over. really stupid mechanic for a porn game.
