I can't really keep track of all the battle royale seasons at this point, but in any case, we're now at Season 9 for PUBG - and you can expect some real fireworks in this one as it introduces volcanic map Paramo.
Paramo is described by PUBG Corp as the game's "first dynamic map", and the latest teaser trailer finally gives us an extended look at its landscapes, although exactly what dynamic means is still up for debate. Some speculate the map will be procedurally generated for each match, which makes sense in the context of the trailer and PUBG Corp's description of a "dynamic landscape [that] will keep you guessing each drop". Others think it may be closer to Karakin's Black Zones, which flatten everything in their path - including buildings. A slightly wackier theory, as explained by PlayerIGN, predicts Paramo's hook is actually time travel. Either way, it's volcanic and dynamic.
PUBG Corp started teasing the map in late September by sending a bunch of stone tablets to influencers, and later followed up with a lore video hinting Paramo is actually the location of the fountain of youth. There have also been several hints pertaining to helicopters being added in the new season, in both a letter accompanying the tablets, a dev tweet and several teaser videos, so it seems likely the vehicles could be introduced as part of Season 9.
Back in July, PUBG Madison studio director Dave Curd told me PUBG Corp wants to be "more lore-forward" and encourage players to be curious about the game's wider universe, which sure seems to be happening here - and with the new PUBG lore site. I guess we'll finally get some answers when Season 9 drops on 21st October for PC, and on the 29th for consoles.
