So here are the groups, at least the ones I have pictures of at the moment:
RAFM Powered Armoured Infantry.
Imperial Troopers from the Laserburn range.
Not sure about these.. Old Traveller minis, I think?
Khurasan aliens and crabmen.
Bountyhunting Bears. Khurasan.
Giant Demon Aliens. Again, Khurasan.
Hope you enjoyed those :) I have hundreds more in the cupboard waiting for paint, so expect more of these.
