Gundam Scenarios

For scenarios involving Gundam, you can use the campaigns outlined at the excellent Gundam site: Mobile Suit Battlesystem.

Mobile Suit Gundam Battlesystem is an excellent system based on Game Workshop mechanics of 40k.  The author also wrote up a neat set of campaign rules for his Gundam battlesystem rules. 

Its relatively easy to take some of the ideas in my previous post and use the scenarios he outlined.
