Developers of Overwatch Jeff Kaplan and Arnold Tsang, in a BlizzCon panel, have revealed a long series of concept art ever seen before relating to the early stages of the game this weekend.

Under the title "Overwatch: Archives", the conference highlighted the initial phase of game development, the transition phase from the deleted OMO of the software house titan Titan. In fact, some of the game's assets were then embedded in Overwatch.

Kaplan and Tsang shared images of heroes, early maps ideas, and even the famous character Jetpack Cat, eliminated at an advanced stage of development. Take a look at the pictures below.
