Absolute Mayhem Trophy in LEGO Batman: Legacy of the Dark Knight

Mayhem Runs start from the hideout in the Amusement Mile once the escape from Arkham Asylum is done. A run ends when you extract or when the timer runs out. Any five finished runs count, whatever you do in them. Collect studs on each run: they extend the timer and pay for the permanent upgrades at Joker-Mite's shop in the hideout.
