SR Open Beta begins with Team Builder and Bot
You can earn each icon by winning a game on each side of the map. Win once on red side? Earn the red side icon. Win a game as the blue team? The blue side icon is yours. Win as red and blue both? You’re the new owner of two nifty icons. Do it at the same time somehow? You’ve broken the internet and your prize is the singularity. The icons will be available for the next several weeks.
Will you get them if you win against Bots or must it be in Team Builder?
Best Answer
There's no information regarding that it is required to play on Team Builder.
However some people on Surrender @ 20 are claiming that you can receive the icons playing Co-Op vs Bots.
So my guess is that you can win the icons in both modes.
Any update and I'll update my answer as well.
