I and my friend were working on this "Jett bounce mechanic" for a really long time and we finally made it more succesful than ever. Improvised for every map and almost every object. We made a video about this with English subtitles and we tried to explain as much as possible how it is done. If you don't want to watch the video I will make a summary in this post and you can get the theorical information.

Click here if you want to guide video.

1- There are certain spots on every map (which can be increased by the effort that players' make.) And you can reach the highest area of the map with just Jett's Tailwind ability in these spots.

2- You need to find a "Bounce object" which should not be taller than an Agent's legs or jump height.

These objects are generally categorized as trash cans, little boxes and cylindrical objects.

3- When you think you find the right object to bounce you need to approach it with average 20-25 degrees.

4- You also need to find a perfect distance to approach this object which is 4-5 agents between you and the bounce object.

5- When you think you did everything correct, you found the perfect object, the perfect angle and the perfect distance, you simply need to use the Tailwind ability and jump almost simultaneously. It differs object to object, sometimes you need to first use the Tailwind and then jump, sometimes first jump and then use the Tailwind.

There are 41 examples in my video and there is detailed explanation but to sum up this is it. I hope this post will helpful.
