This is from a wargame called All Quiet on the martian front.
It is basically a tabletop wargame based on HG Wells The War of the Worlds. At the moment they only have the martian, British and American factions but they are also planning to add the Moon people, Venusians and several more earth factions.
I really like the design of the aliens. They actually look alien and not like weirdly coloured humans.
