Unreleased sets and prototypes

So my brain decided to remember the unreleased stuff I seen years back, so I’m here showing it to you all, in case you’ve never seen it. The first is a supply pad from halo wars, I’m disappointed this never came out, cause some parts in it look pretty useful, not to mention it looked nice. The second, I’m not sure really what was it, I suppose the Vulcan was supposed to be included with a revenant and a turret, or if that was the name of the turret. The third is a prototype of the Covenant Strike, which did come out, but was pretty hard to find. The fourth is a really interesting one, it was a planned forerunner structure set with some flood in it, and the build looks similar to the towers found in Valhalla, a big shame it was canceled. The last two, I’m pretty sure were a prototype of the phantom, which seemed way more blocky than its actual release in 2011, I’d say the worst thing about this is that hood piece, just nasty. Overall I’d say the supply pad and the forerunner structure should’ve came out. What do you guys think? Would you’ve like to see some of these be a real product?
