I've been playing my Noise Marine army most of the time lately with Slaanesh allies in the form of Seeker Chariots, a Keeper of Secrets and Fiends. Heldrakes and Blastmasters are good. So is the Brand of Skallythrax. Doom Sirens are situationally awesome. Seeker Chariots and Keepers of Secrets draw the heat. Forgefiends of both varieties are pretty hit or miss, needing the right targets to be any good. Maulerfiends are surprisingly useful if properly supported.
I haven't posted much lately because much of my time has been spent getting the army constructed and painted. The Heldrake is quite a bear to paint up lemme tell you whut. I've got a ton of work left to do. It is depressing.
Anywho, I want to run Chaos Havocs with flakk missiles and Slaanesh bikers with meltaguns, but if you want a meltagun that fits on a bike you have to pay like 15 bucks for a biker upgrade pack that includes exactly one one plus a flamer. If you want Havocs, they only sell five finecast Havocs with a royal sampler of heavy weapons (1 of each), which is stupid. And finding missile launcher Havocs on Ebay is an expensive chore.
I have arrived at a solution. Forgeworld produces Horus Heresy era weapons packs that include missile launchers and meltaguns. They can be found here.
It will set you back $35 bucks, but you get four missile launchers that you can nail onto some CSMs, and four meltaguns for bikers, or for whomever else, since you only get one stinking meltagun in a pack of CSMs. As you can see, the FW meltaguns fit perfectly onto the CSM bike with just a bit of knife work. For some reason, Blogger uploaded the photo vertically, even though the image was not taken like that. Just turn your screen sideways and it'll be fine.
The flamers can be used on the bikes as well, or you can convert a couple of them to create a Burning Brand of Skalathrax, so you get a lot of mileage out of your $35.
