AVATAR concept design

here's a little bit of the concept work i did for avatar.
these are weapon designs for the RDA security forces on pandora.
i really went super nerdy designing these things, and worked out all the little details, like the reloading process (pre-packaged plastic magazines that you tear the top off and load, complete with e-ink ammo counter on the sides. then you twist the top dial to chamber and cock the first round), how the modular pieces form various weapon types (the under barrel grenade launcher on the assault version forms the base of the shotgun/20mm munition launcher) etc etc etc good fun! these versions are the original caseless designs, but the finals in the film had cased munitions, and ejection ports, as jim wanted brass flying. he also asked for the shotgun to be pump action, which was fucking awesome cause pumping the final prop (with norinco 12 gauge pump internals) is a highlight of my time at weta.
