Man that was hard!
Anyone other than me found the movie cutscenes a bit outdated?
I actually had to resolve to the hints to complete it;
The Brik terrain type is an obstacle you must learn how to overcome. You aren't able to go through Brik (except with the SUPER INVISIBILITY CHEAT) so make sure you work on alternate routes to take you out of Brik's way!!
Keep Yer Cool!
Like all great quests there will be times when you don't know what to do. The best thing to do is relax and stay focused! Be observant and try anything NO MATTER HOW CRAZY IT MAY SEEM. And remember, this is a game so most importantly HAVE FUN!
Get the Crown!!
Do not get distracted by side-quests and obstacles. Once you solve a puzzle, get back to the main task at hand and find that bloody crown!
