Just my Covenant weapons. I know the Fuel Rod Gun/Cannon doesn't look like that, but I guess I based it off of Halo: CE. I don't have the Brute Spiker because I can't figure out a way to build it without cutting any pieces...
Plasma Rifle. I was so proud of this one that I built another one and had one of my elites dual-wield these in the face of a Spartan.
Brute Plasma Rifle
Covenant Carbine. I know it lacks the butt, but the minifig couldn't hold it if it had the stock thing.
Needler V2. This was actually pretty easy to build.
The Energy Sword. I was surprised by how hard it was for many people to make a nice Sword without cutting pieces *coughScorpcough* or using lightsabers.
The Beam Rifle. Nice? Yes. Taken from Felix Westin? Yes. Now I've built a better one that looks like the Carbine, thanks to Spartan 9056's review. Thanks man!
The Fuel Rod Gun/Cannon. I know it sucks.
I just couldn't resist putting my minifig Hunter here. I know he's not to scale with the other 'figs, but he's not supposed to be.
And finally, the Brute Shot. Or the n00b shot as I like to call it.
Awesome armor, You got some drawing skills there, friend. And Emperor Warlock, if I were you I would learn to make some real models before spamming MOCpages with random 1-star reviews. So go home and stay there, because racists don't belong here.
