Batman™: The Dark Knight Challenge

Gotham City, a metropolis plagued by crime and injustice, is in dire need of heroes. In response to the escalating threats, Batman has initiated a new Gotham City Guardian training program. You have been carefully selected for the program to attempt a new and intense training exercise that includes stopping a training device Batman planted in the heart of Gotham City filled with a non-harmful chemical compound designed to mimic a legitimate chemical leak without the fatality. The device is fitted with a countdown clock that will release the gas in exactly 60 minutes after your mission start time, so you'll have to work quickly.
