Warlord Games gives you more options to customize your minis with the new weapons packs available over in their webshop.

Unleash a storm of firepower onto the streets of Mega-City One!
This new range of weapons sprues allows you to re-equip your gang members as they gain experience and creds over the course of a campaign. Of course, they’ll work well for other sci-fi games too!
