The Chronicles of Narnia: The Lion, The Witch and The Wardrobe Hints for XBox
When two people are playing this game simultaneously, the best strategy for some areas may be for one of the players to temporarily 'drop-out' and let the computer take over three of the characters movements.
Once past the difficult scene, then the second player can re-enter the game by dropping back in. This is useful in some areas where you need to sneak, especially when you need to play as Susan in order to get past the sentries that are stationed in front of tents.
It is also useful to do when trying to scale over the thin ice without falling in, as well as in a couple of battle scenes.
