Thanks to a new Overwatch clip, a new map detail has been discovered: you can ring the bell across the lake at Chateau Guillard. The clip was posted on the Overwatch subreddit by "DeSensedTTV" and shows him shoot the bell in Annecy, a city near the real Chateau Gaillard, and hear the ringing sound.
Some comments on the Reddit post complained that there was no sound delay like there would be in real life because the bullet has to travel to the bell and the sound has to travel back, but it is still a very interesting detail to include in the game.
It isn't the only map with these small details. Petra has lore, both Route 66 and Blizzard World have coins that explode out when you shoot the pay phones and treasure chest respectively, and a new update has made it so the basketballs in Ilios, Nepal, and Lijiang Tower can be reset by clicking F.
