What riders love
  • This thing is one of the few coasters that makes me nervous. I love the suspense of the lift and the sheer size is great.
  • Suuuuuper intense.
  • Giant Boomerangs are beasts, the intimidating vertical spikes, intense compact layout, great for smaller parks.
  • Definitely the scariest roller coaster I've ridden, (not actual hangtime) but the vertical ascent up that first spike before the drop has you hanging into your restraint high up there.
  • When the train horn sounds (yes, they sound a train horn) and you are dragged up the 190-foot spike, its the perfect fear factor.
  • Furthermore, Vekoma did SOMETHING to the trains to make the coaster buttery smooth for an old-gen Vekoma (still not very smooth, but exceptional for its time).
  • The coaster is relatively smooth for what it is.

Vs. other coasters at Silverwood Theme Park

I can get some decent air on the transitions of the cobra roll, and some pretty powerful positives on the vertical loop (especially going backwards) but at times they can be too powerful and give me a...

The ride is shockingly smooth for a Vekoma from this time period (not sure if other GIBs are this smooth), and everything from the first drop to getting winched back into the station is pure...

This coaster is still an old-gen Vekoma, and it is very rattly, with the bulky over-the-shoulder restraints not helping.

Bradley D.

The beginning is amazing but like other Vekoma rides you end up hitting your head on the restraints.

Also really great for re-rides/marathoning despite its intensity because of how smooth it is, but don’t expect to be able to on a busy day with that shuttle coaster capacity.

Evangelion Martini

Adrenaline at its best! This thing scared me to death going slowly up that vertical spike backwards!

CoasterKiwi

Suuuuuper intense.

Alexia Englund

For a ride that doesn’t put much stress on your body, it is incredibly intense.

@joeboo8626

I went on this ride and I’m shook it was so intense and I absolutely loved it

@TLGRIER

It’s only scary at the first drop, after that you’re going so fast you can barely tell you’re upside down and the cobra rolls just jerk you.

@NextGENDubstep2013

Prepare for headbanging on the cobra roll and sloowwww dispatches.

Oh gosh that feeling of just the ride lifting the train up the lift hill is gosh darn scary.

Really fun ride, and its really higher than a 3....but in comparison to others......

Will Anderson, Captain Coaster review

The ride is shockingly smooth for a Vekoma from this time period (not sure if other GIBs are this smooth), and everything from the first drop to getting winched back into the station is pure pulse-pounding fun.

Evangelion Martini, Captain Coaster review

Going up before the first drop, the view of the mountains and everything is AMAZING.
