I recently discovered that (in the E3 demo) Malus can be triggered in any location within its own map square. That is, I first have to find the position co-ordinates of Malus (before activation) when it's a 'ghost model' with no collision detection... then I can move it to some other location that I want.
Next, I move Wander to the original 'trigger point' and then use a camera hack to see what happens from the colossus view point... I guess it's hard to explain here, just watch the video and you will see what I mean ; )
Note: the 'beeps' you hear are when the colossus cut scene 'changes' from scene to scene.
Enjoy!
