Revealed to be present in the game files at the end of last month, the Fly Explosives LTM is described as follows:

“This mode combines the explosive fun of the High Explosives LTM and the vaulted Limited Time Item Jetpack. Take to the skies and blast everyone else back to the lobby!”

As of today, a new Playlist image titled BR05_LTM_FlyExplosives has been added, suggesting it’ll release soon:

With Guided Missiles returning tomorrow, it would be a perfect time to release the mode. As usual with this kind of information, no official announcement has been made and nothing is confirmed.
