Hardest Co-op in the game

Definitely the boss difficulty of the coop. There's no movement, but it's extremely difficult to clear and get a good grade. Warning: If you twist too intensely, you might get stomach cramps, so I recommend warming up your body before starting. Finding a single-player UCS to practice separately is also an option.
