Yup. Here are the contestants:
On the left, Boba Fett holding a laser rifle, with a clip-on grenade launcher, blaster pistol, and customized ion rifle at his disposal, in addition to three concussion and three ion grenades.
In the middle, Master Chief, holding his MA5C and M7, also ready to use a plasma sword or plasma grenade.
On the right, the Space Marine, with Power Sword and Bolter, a Mini-Bolter at his feet.
I'm going to use the grey studs in the forground for standard frag and krak grenades, and thermal detonators.
Note that not all of the characters' available weaponry is shown, each character will basically have a small home room containing an arsenal of weaponry, from which he can choose as desired. I'm not going to include the chainsword after all. It'd be a pain to build, and doesn't seem to have any real advantage over the Power Sword (aside from general coolness).
The terrain should be done soon, so the war will (ideally) be ready by Astarte.
