Well, with 15mm having bitten me big time, how could you not go for a few zombies? I love a good zombie movie and I've picked up a bunch of zombie starter packs from Rebel Mins. In a few weeks, I'm going to be the proud owner of some 60 15mm zombie figures.
I picked up the rules for Ambush Z, from the vendors of Ambush Alley. They are rules for skirmish games in 15mm and have options for solo play. They look good.
the rules seem to be more scenario based rather than just straight army battles. Time to watch some of George Romeo's zombie movies and get some ideas.
