Demon596 = Legend!
This glitched first time round (grrr), so I followed the guide.
Used codes to get: Fast Build, Invincibility & Mini-kit detector
And various characters including Cad Bane - since you'll need a hover guy for one level, etc.
Didn't always get the multiple items for a kit in order (I don't think it's always possible) and it popped on 7/10 on Grievous Intrigue (didn't need to play Zillo or Castle levels).
Thanks very much, Demon - feel free to go work for TT some time soon.
