Shadow and Sonic share a bond that's quiet... complicated. To Shadow, Sonic is a foe, sometimes a rival, yet deep down, there's a level of respect he can't deny. But beneath it all, buried so deep even he refuses to acknowledge it, lies something else-something unspoken. On a mission to wipe out Eggman's endless army of robots, Shadow never expected Sonic to show up, claiming that G.U.N. had sent him to help. Together, they set out to locate the core of the machines.. Neither of them realized it yet, but that mission? It was about to change everything.
