Zofia has the 2 grenades (impact and disorienting) that she can switch between, the latter being able ti bounce I believe.
Vigil becomes invisible to drones but drones have a UI to show he is in the area.
Dokkaebi hacks defensers phones creating a lpid noise that must be turned off. If she can get to a defender body she can hack into the camera system, although Echo is immune.
Weapons seem to be experimenting, 2 shot shotguns, another LMG, defender carbine, 2 autopistols. Lots of new stuff.
