It's in a BundleStars bundle for $5 with about ten other games: http://www.bundlestars.com/all-bundles/vendetta-bundle/I actually had fun with that game as well, in the demo. Planned to get it on sale, never saw it happen. Next time I guess.
Thanks, it and the Sniper game are probably worth $5. Steam version of Disciples 3 can't hurt I guess. Rest is trash. Worth it though.
