This is the Republic Stealth Interceptor. Same colors as the Death Commandos, but I don't care.
About this creation
Front view. The second cannon is under the front part.
Overhead view. The front is a little too bulky, but that's because LDD didn't have the parts I needed.
Rear view. The engines look too small for the craft, but in Star Wars, anything is possible. Especially a 20-mile-long Super Star Destroyer flying around (not the Executor, this one is bigger) with just five small engines. And a miniature Death Star gun mounted on the front of that same ship, just to be ridiculous.
And yet another random Halo picture showing the 5th coolest Halo character.
