A new hero, a new adventure! Help Jack escape Dr. Jaykovich's evil train!
Get off the rocket where you're trapped and run for your life! Jump over the explosive barrels, slide under those deadly lasers, run over the walls to avoid the acid pool or over the roof of the wagons to get more coins.
Jack can improve his ability to jump, glide, walk over walls, fly and much more. Using these skills you'll be able to go further each time on a train full of traps and deadly devices.
So you're telling me there's a "Ninja Jack" achievement but there is no actual ninja skin?
