Re: Curious about SGII

I would use SG2 or an FMA-type skirmish system.

Specifically, SG2 works for squad vs. squad, and the cramped hallways of
a
spacecraft might be better suited to smaller scale skirmish rules, such
as
Andy Cowell's rules (GW's Necromunda and Space Hulk vs. 40K is the GW
analogy).

For a quick and dirty, GW's Space Hulk or ICE's Explosive Decompression
would be quite good.
