From the update:
This week we have some more artwork for the book. These are Fortune hunters for the second wave of models, reinforcements if you will. Included are the Silent Soldier, a stealthy killer that uses ancient ether tech optics to see in multiple wavelengths, allowing it to detect camouflaged enemies and see through any obscuring material in the water. Also coming is the Big Game Hunter, a tracker and killer of all wild creatures, blasting them with a powerful harpoon gun. Last is the Assistant Mech, a small mechanical construct that the Fortune Hunter scientists have salvaged, rebuilt and reprogrammed to help them find and use ether tech artifacts.
