Nemesis at Alton Towers is an inverted coaster manufactured by Bolliger & Mabillard.  It consists of two trains with eight cars seating four across, for a total of 32 riders.  Upon dispatch the train veers slightly right out of the station before ascending the chain lift hill and plunging 104 feet to the left into a corkscrew.  It then enters a downward helix and goes up into a zero-g roll.  This is followed by a vertical loop and corkscrew.  It traverses what might best be described as a horseshoe configuration before entering the vertical loop.  After the final corkscrew the train speeds through an underground tunnel before returning to the station.

While limited as to the number of elements, Nemesis offers a very intense ride.  The inversions flow nicely and don’t give the riders much of an opportunity to catch their breath.  And although rough in spots, Nemesis is enjoyable enough to merit repeat rides.  4 out of 5 stars.  For more information about rides at Alton Towers, visit https://www.altontowers.com
