Bad news, work stole my last six weeks from me. Good News, Onslaught Miniatures released their Kaiju Mega Rig during my absence!! A painted version is available on the Onslaught Miniatures Facebook page here.
Onslaught miniatures are a great source for players looking at trying out 6mm sci-fi rulesets. Their product is high quality and the customer service is excellent. I have purchased their Stygian range (Dark Eldar proxies) and have seen their OTC range (Tau proxies) across the table in a number of tournaments.
Head on over to their site and check out their range of 6mm miniatures.
