Universal Orlando has announced the latest horror maze for its Halloween Horror Nights 2013 events - a "sequel" to 2010's Havoc: Dogs of War.
The original maze featured crazed soliders, driven mad by a combination of powerful drugs designed to enhance their bodies. In 2013, the "Dogs of War" will be set loose on a derailed train convoy, once again terrorising guests.
The design documents below show off the derailed train that will feature in Havoc 2: Derailed.
Hosted at Universal Studios Florida, Halloween Horror Nights 2013 will start on September 20, continuing on select nights through November 2.
