Worldsmith Industries has unlocked the Human Corps wreck markers over on their Kickstarter. Next is Space Elves.
From the update:
Thanks to your support, the Human Corps wrecks have been unlocked! The Human Corp Walkers are now available as a Category A wreck, and the Human Corp Transport Tank (which is sized correctly for vehicles built on a transport or battle tank chassis) is available as a Category C wreck.
Next for your consideration, I present to you a veritable Space Elfapalooza. When the elves left Middle Earth, the other races were a bit relieved. While elves are beautiful, and graceful, and long-lived, they’re also pretty full of themselves. Frankly, they’re jerks. You can imagine, therefore, the disappointment of the human race once they took to the stars and rediscovered their old friends, the elves. It turns out the space elves are just as insufferable as elves, and their long stint wandering the galaxy did nothing to instill a sense of modesty in them. Thus, when they took to battling one another, the other races took particular delight in watching the space elf vehicles explode.
