I'm trying out the Game Journal feature here, which I haven't used before. Bear with me :-)
Horde was my entry in the GDS here in January 2012. The initial entry is here.
I've worked some more on it, expanded and changed the rules, generated a prototype, and I'd appreciate any feedback people could offer. I'll link some pictures and the rules here. If anyone is willing to playtest, let me know; I can whip up a P&P version pretty quickly, or I may be able to arrange to have a full version sent.
Rules are attached as PDF below; please read them if you can and let me know if things are clear. I'd appreciate any comments at all, for that matter.
There's some more commentary on my blog: http://planktongames.blogspot.com/search/label/Horde
