Rainbow Six Siege and Overwatch are often held up as great examples of evolving games, with Ubisoft and Blizzard continuing to support their multiplayer titles long after their respective release dates. Both games are excellent team-based multiplayer shooters, both utilize a hero system to add depth and replayability, and both have very passionate fanbases. But which game is better?

Our new show, Versus, kicks off with an episode dedicated to pitting the two shooters against one another. Seasoned Overwatch player Tamoor Hussain is in the red corner, fighting for Blizzard's colorful shooter over a three-round argument. Oscar Dayus, meanwhile, is over in the blue corner championing Rainbow Six Siege. Be sure to watch till the end to see the quick-fire round... it goes places.
