The first Blizzard game coming to Steam will be Overwatch 2, and it’ll be available on August 10th — just in time for Steamers (that’s what they’re called, right?) to participate in the Overwatch 2: Invasion event that introduces the long-awaited PvE story missions.
Yeah just like ea and ubi games. You can buy them on steam but when you launch them it opens the respective launcher and then launches. I just did it with rocket League the other day because I have it on steam but I put some old parts together for daughter to have her own PC and you can only get rocket league through epic. So I installed the added it to steam so she can launch it right from there.
