Apocalypse is a steel stand-up roller coaster located at Six Flags America in Prince George’s County, Maryland. The ride made its debut in 1990 as Iron Wolf at Six Flags Great America before being relocated to Six Flags America and renamed to Apocalypse. The roller coaster was the first built by Swiss manufacturer Bolliger & Mabillard. When known as Iron Wolf, the roller coaster held the records of the highest (100-foot or 30-metre) and fastest (55 miles per hour or 89 kilometres per hour) stand-up looping roller coaster in the world before losing them to other roller coasters in 1992 and 1996.

Ride experience

After departing the station, the train makes a 180 degree turn leading to the 100-foot (30 m) chain lift hill. Once at the top, the train goes through a pre-drop before making a sharp left hand turn leading into the first drop. Once the train is at the bottom of the first drop, it immediately goes through the first of two inversions, a vertical loop. The train then makes an upward right turn before making a left turn back down to the ground.

The train continues to go left before going through an upward helix. After, the train makes a downward right s-bend leading into the second and final inversion, a corkscrew. The train makes a left turn back up before going through another s-bend, small over-banked turn which leads to the brake run. One cycle lasts about 2 minutes with riders reaching a top speed of 55 miles per hour (89 km/h).
