Gamma World 4e ruleset?

[adzling]

Hiya, does anyone know how to play Gamma World 4e on FGU?

FYI 4e is close to D&D 3e in many ways

I found the old gamma world 2e pak but it's useless.

I am happy to put the work in to customize character sheets and add powaz and stuff just need a good starting point.

XCore is a good starting point. You can probably get everything you need as is, but you can create a XCore theme as well if desired.
