Battleborn's Thorn, an elf-like archer, and Miko, a… mushroom, will both be playable musicians in Rock Band 4 soon.
Additional details are scarce right now, but this isn't the first time Gearbox has partnered with Harmonix to craft a bizarre, unexpected cameo appearance. Last year, Borderlands' Nisha the Lawbringer and Claptrap were both unlockable dancers in Dance Central: Spotlight. Unlocking Nisha and Claptrap in the Dance Central was actually free and only required the input of a code. Hopefully that is also the case here.

I'm a fan of these strange overlaps that occur in video gaming every now and then. It's also nice to see Harmonix and Gearbox be so friendly, even though they make very different games.
