Right now its like this...
DoomGuy has moved up through the army, leaving a bunch of death behind him, but is MIA ATM. Hes somewhere near the base's outer walls leaving a huge hole in it.
Roy Mustang is going suicidal on Dirty Slime's character group. Gun's char is also fighting some of that group as well. Light is following Roy but will be taking his corpse back to the ship if he dies. Most of the Resistance forces are around this spot, but you can jump in somewhere else if you want.
MC, Bayonetta, Ridley, Penny, Absolis' char, Kid Flash, Tex's char, and another character I can't remember are in the Mess Hall of the enemy base fighting. MC summoned a bunch of poison elementals which are fighting a bunch of soldiers, and is ready to make a portal out of that place when everyone is ready.
Wizard's char and Gentleman's char are talking in the field of battle.
Dunno where Letter Bee's char is.
There are two other people I'm not sure where they are, but I assume they're fighting in the field of battle somewhere.
