Two Dots are a creative studio who specialise in promotional and cover art. Think book covers, box art, collector's editions, posters, etc. Recently they have worked on games like Assassin's Creed Syndicate, Far Cry 4, Elite: Dangerous and Assassin's Creed Unity.
They have also worked at a more conceptual stage on games like Watch Dogs. The Far Cry 4 stuff is particularly interesting, especially the different box art ideas.
