is a team-based shooter that includes 21 characters, each of whom handles completely differently from the rest. But the recently-launched title has a key difference from other team-based games — you can change characters at almost any time, and in fact, the key to winning is often in changing the character you’re playing as based on the situation you face.

Unfortunately, not everyone playing gets that which characters you use together, or what situations you’re taking them into, is really, important to winning. So you’ll often find yourself playing matches in which an attacking team has defense characters such as Torbjorn and Bastion, or a defending team that thinks it should definitely have three Genjis. With a few key tips, though, you and your teammates will be able to construct better teams with better success rates. It’s all about working together to amplify your characters’ strengths while covering their weaknesses.
