I've bought a bunch of the unlockable characters, including the Bazooka Trooper. So now I want to go back and explode some silver! The problem I'm having is, having done that, I can't seem to select the team I want to. I get one choice of character; and when I choose them, they replace Indy. Which means I'm stuck at the first whip swing. I'm pretty sure most of the other characters used in story mode are required to complete the level, as well.
So, how do I add / replace other characters instead of Indy, to create a team that can actually complete the level?
Note: This is the Xbox 360 version, if that makes a difference.
