A crossover between Diablo 4 and Overwatch should be an easy win. They're both owned by Blizzard, and they each have huge fanbases who generally love aesthetics and a bit of novelty. The in-game rewards are all well and good, but the action-RPG's new skins from the FPS aren't getting the strongest reaction from players.
Just like World of Warcraft and Starcraft before it, Overwatch is stepping into the hellfire of Diablo 4. Starting June 30, you can earn Eye of the Overwatch currency through defeating Elite and Champion foes to spend on special loot, for a limited time. In the game's regular shop, you'll find skins themed around the hero shooter, though players don't seem too fussed about those from first impressions.
