Relevant details:
14 bosses
11 bosses will have Sarth-style hard modes (example given is the boss of the vehicle section, you can take out the defense towers in the area before killing the tank boss to make it easier or leave them up)
Apparently the dungeon will be separated into two parts, the first being a vehicle section where you take on the massive army guarding the main dungeon, the second being the actual dungeon
