The chief appeal of Twin Souls: The Path of Shadows is that it looks a bit like beloved stealth action series Tenchu. Also, you have weird shadow powers, which is cool. Despite these facts, it failed to meet its Kickstarter target (opens in new tab) during a crowdfunding attempt last year. Development has continued anyway, and that's a good thing, because this latest slice of game footage looks great.
It highlights a number of your abilities, from shadow-to-shadow teleporting, to the ability to paint the ground with shadow. It's a bit like Splatoon, but for goths.
An E3 trailer appeared a couple of weeks ago (opens in new tab), alongside a Spring 2016 release window.
