Life Is Strange 2 remains shrouded in mystery, but Dontnod’s free, downloadable prequel-of-sorts, The Awesome Adventures of Captain Spirit, gives us our first taste of what we might expect from the sequel. And even with its brief running time, differing perspective and vague conclusion, Captain Spirit suggests that the next Life Is Strange game will be even more gorgeous and fantastical than before.
[Warning: Full details about the plot of Captain Spirit are below. But the game is both free and short enough to finish in one sitting, so you can go play it and then come back here!]
