The colorful hero shooter game Overwatch can give you a whirl for free.
If you somehow haven't started trying Overwatch yet, now is the time to do it. The game is currently free until January 2nd, allowing you to dip your finger in the hero shooter waters.
The free trial is unlimited; You can access the entire list of characters and mods, play, level up and collect loot boxes like everyone else. If you connect and decide to purchase the game, any progress you make will continue without trying, as long as you use the same Blizzard account. Overwatch has also just launched its Winter Wonderland event, so you can play weekly challenges and find new outfits for Tracer, Symmetra, and Zarya.
