Welcome to Switch Funday.
I teased it in yesterday's video, https://youtu.be/RRILIgS2XWU, that i was going to try and do the first Challenge Event. i managed to get in 10 battles, winning 4, before i ran out of time.
What you'll hear throughout a lot of this video is confusion as i try to work out how this Challenge Event works. whilst the new weapons were all clearly shown, i feel like what this event is wasn't explained clearly enough. i feel that by the end, i got somewhat of a grasp of what this was all about. i'll try to explain it, but feel free to add in the comments if i make a mistake.
For the first Challenge Event, the challenge was simply playing the two new levels that were added in patch 4.0.0 (the Sizzle Update). a restriction was that only the primary ability of your gear would be activated (the first pin on your gear, not any other pins). A level/score for your ability is created over 5 matches. for me that was 808. any wins after that increases that score, whilst losses reduce that score. (i tried to show this a couple of times in this video). the "winners" are those who rank with the highest scores. you could play any of the three time slots, your highest score across all three would be your final score.
Looking at the Splatoon 3 Wiki, https://splatoonwiki.org/wiki/Challenge, it seems there's another challenge on June 6th so i may have a go trying to get in at least 1 time slot. the following other Challenges are listed but i don't know if i'll have time to try them all. but the challenge on 15th June sounds fun as i'll get to try out randomly selected weapons.
