Awesome! - Glad yours arrived safely too; Post photos!
Weapons-wise I had the Metal Weapons 3-Pack to-hand but it seems at the moment people are just using weapons from other lines that are "1:18"/"3.75"/"G.I. Joe" sized.
I've found some of the Marvel Universe figure's weapons work alright, so too modern Thundercats stuff.
Might have to wait and see if October Toys will do a Weapons Pack as part of Grimskull's upcoming Kickstarter?![]()
