Oblivion

"'Oblivion beckons you to face your fears. As you’re held, overhanging the edge of the world’s first vertical drop rollercoaster, you get a moment to savor what is to come.'""- Oblivion’s description from the official Alton Towers website"Oblivion, otherwise known as Secret Weapon 4 (SW4), opened to the public on March 14th, 1998. Like it’s nickname suggests, it was the fourth Secret Weapon to be created after Nemesis (although it is only the second one to actually be built). It is a steel dive coaster and was manufactured by Bolliger & Mabillard. Oblivion resides in X Sector and is located directly across from The Smiler.

Post-Ministry
When X Sector got the Ministry of Joy revamp, Oblivion’s lore was changed drastically.
