wierd ww2 germans with wierd weapons
All of these are already available from elsewhere my friend (Blackcat for the robots, Westwind and others for WWW2). Remember that the range needs to compliment each other, as it's doing so well already. I've seen a number of great new ventures go off and sculpt everything, but with nothing really holding them together, they end up part ranges or pet projects and not really useable.
Ok back to the suggestions:
All girl post apoc gang, (but not hyper sexy in a overt sucker punch way) just 'bullet' hard but with a definate femininity.
Gunners, drivers and passengers: A pack of minis that you could use in say 1/43-1/50 scaled diecast cars, also the gunner option comes with a 30 or 50cal to mount on the back of a flatbed or technical.
Gaunts: really emacitated, S&M styled gang, (think Merv's gang in Matrix revolutions...Hey Merv...what's it gonna be?).
More corpses: just without weapons and gasmasks so could pass as civilians or dead zeds....
There you go a few ideas for the pot.
