Crossover Miniatures are running a Kickstarter to produce a new game: UFO Squad. The project is of produce a set of Grey aliens with support, some human troops and a dropship (in MDF). They intend to use rules based on the ‘Song of…’ game engine from Ganesha Games.
This looks an interesting project, although I’m a little disappointed that you simply cannot pledge for a copy of the rules (fans of this genre may well have minis already – although the ‘Grey’ aliens are nice)
At time of writing it’s less than $300 away from being funded, so might well be worth a look.
