If you ever wanted to give Overwatch a try, but you weren't sure if its the type of FPS you'd enjoy, you're in luck as Blizzard has just announced a free weekend. From November 17th at 11am PT until November 20th at 11:59pm PT Overwatch will be free to play across all regions and platforms.
As with all of the previous free weekends, the upcoming one will give you access to all of the content besides Competitive Play, for obvious reasons. Most importantly of all, the free weekend will include the 26th hero Moira which is currently on the PTR! Whether this means she'll be patched in next Tuesday during the usual update period, I don't know, but Blizzard has clearly stated that the new players will have access to all "26 heroes", so look forward to seeing Moira and her accompanying balance changes in the near future.
On a slightly different note, it is worth mentioning that the free weekend will not feature the newly announced Blizzard World map or cosmetics themed after other Blizzard games. They're both supposed to arrive very soon, though when exactly that might be only Blizzard currently knows. I've heard people mention that the new map will be here in early 2018, though I couldn't find the exact source, so take that with a few grains of salt.
And finally, let me send you off with an image highlighting the free trial starting time for most of the major time zones:
