Season 1 was the very first season of Fortnite: Battle Royale, which started on October 25th, 2017, and ended on December 13th, 2017. It was also the shortest season, lasting only 43 days, compared to the average 74 days. This was the first season to use the Athena island/map.
It was only the beginning, so there weren't many things to do around here.
For the first time, progressing through the game allowed you to get rewards that could be purchased for V-Bucks, which unless you have Save The World, can be obtained through in-game purchases for real money.
XP Progression System
Unlike the following seasons, it had no Battle Pass. Instead, it used an XP progression system, wherein you unlocked rewards to purchase by getting XP from regular Battle Royale games. As mentioned above, you needed to have V-Bucks to actually get them.This progression system was taken away with the introduction of the Battle Pass in Season 2, and was reintroduced with a few alterations in Chapter 2: Season 1.
