There are now army profile cards available to let you use your AT-43 figures with the free No Limits sci-fi rules.
From their announcement:
The defunct Rackham range lives on with some help from Tom Kiley and his After Trauma army profile cards for No Limits.
These pre-painted plastics were a nice range with a good selection of models released for four main factions.
Tom’s profile cards have all the important information in one place for your Rackham models.
More profiles cards will follow in the next few weeks for the Therians, the Red Blok and the Karmans.
