2.Willard's Lair
3.Shakespeare's Cliff
4.Sleeping with the Fishes
5.It's a Madhouse!
6.Reunion
1.Highland Fling:The atmosphere of this level is charming. The graphic designers did a very good job and managed to make you feel as if you were in Scotland. You explore Willard's castle-his guards, their dogs and some crows will be there for you to "play". The level is not very big and your main aim is to find two thistle stones that will open the entrance to Willard's Lair. Have fun climbing and trying not to make a wrong step in the mist! Oh, and be careful, you might be able to catch a glimpse of Nessie.
2.Willard's Lair:This level is not very big either and it is full of spike and boulder traps. There are two paths which you can follow to finish the level-the first one is easy ,but the other one is more difficult-"Abandon Hope all ya who enter here"-and requires you to be good at making combo jumps with the correct timing. Inside Willard's Lair, you'll find the Cairn Key. You have to solve a rather hard puzzle in the library to proceed.
3.Shakespeare's Cliff:You have to get to a place in the English railways where there has been an explosion. You'll have a nice time with the quadbike. Get used to the controls because in some places, you have to control the quadbike very well, or you'll end up crashing onto some strange poisonous material-credits go to Dr.Willard for that. You also have to do some combo jumps with roll to avoid a drill and some flames. Your aim is to find the appropriate passes and keys to activate a drill that will open the door to the next level.
4.Sleeping with the Fishes:This level is quite big and complicated. At first, you get to explore a huge underwater area, where you have to find and press switches and get to the surface in time, while fighting with lots of scuba divers and ugly mutant fish. In the second area, after having pushed and pulled some blocks, you can grab the "Hand of Randthmore" and escape.
5.It's Madhouse!:This particular level can be very small if you are not after the secrets. It starts in a zoo in France-take care of the white tigers that make no noise before they attack and of the monkeys that tend to steal shiny items. It ends in a rather bizarre area in the underground Paris though, where the next level will take place.
6.Reunion:This level has a very dynamic start: a huge boulder coming towards you. After solving a puzzle with some squares that are more solid than they seem to be, you face Sophia Leigh, who won't be vulnerable unless you take her to the highest platform of the area. Take care of some people that want to burn or hit you to death and of course, of Sophia's harmful energy bolts. After you've finished her off, you can retrieve the precious "Hand of Randthmore" artifact and return home in a hot air balloon.
