Blizzard Vice President Jeff Kaplan took to the airwaves earlier today to introduce Overwatch Workshop that is already live on the OW PTR. Players will be able to "craft your marvelous creations!" It is a scripting mode that allows players to make custom game modes within the custom games browser and to prototype custom Overwatch heroes with the system. This feature will be available for PC and console. Kaplan said it is important to note that this is NOT a map editor.
According to Kaplan, two programmers were assigned to Workshop "to give the players some of the power we have as programmers and as game developers to make whatever they could come up with, wherever their imaginations would take them."
Kaplan did provide a caveat that this system may be more for a "power user" that is familiar with scripting language or with programming backgrounds, "really anyone who understands the logic of game making and how game events are sort of chained together".
