Tracer’s biggest ability is being able to teleport horizontally to a short distance. On top of that, she can rewind herself thanks to an ability called Recall. Basically, she can go back a few seconds, returning to her health, ammo, stats and location.
Another useful thing are the Sticky Bomb she carries and judging from the footage above, she can use these to a great effect. Without a doubt, Tracer will make a huge difference for her team.
Overwatch is currently in beta but the game will soon be released on PC.
