Development
This tournament has been announced along with SSAS Trials 3 which had been scheduled for taping and broadcast for almost 4 months. However, the host cwrpg02 have been struggling during the development of this tournament. It is reported that this tournament was originally scheduled to air on SSAS's first anniversary, which is on April 14, 2021. The tournament had indirectly been delayed indefinitely due to consecutive delays caused from the tapings of SSAS Trials 3, as well as the hiatus of ĐHN SASUKE, in which has been announced its tenth season along with the third trials season but nothing has been happened until its cancellation in May 2021.

On April 30, 2021, it is announced by cwrpg02 that the whole show officially enters a 2-week hiatus. This ultimately delayed the tournament to May 2021. Shortly after SSAS Trials 3's taping, it has reported that SSAS 13 had started its production. The taping of the show was notably started on May 17, 2021 and will be expected to air in late May.

It was reported that the tapings of the show have ended on May 21, 2021. The First Stage was taped on May 17, 2021 until May 20, 2021. While the remaining stages were taped between May 20, 2021 and May 21, 2021.

Tournament Summary
Due to the course's extreme difficulty in the previous tournament, the First Stage was moderately modified to make the course easier. In the First Stage, two new obstacles were introduced, Tarzan Rope Kai, which somewhat adapted from a part of Rope Jungle, and Captain's Cabin from VIKING, in which the only difference being the absence of motor usage. Two existing obstacles served a modification, the Rope Glider which was modified to decrease it's overall velocity, and the Dragon Drop where the second track was placed slightly lower in order to have a lower knockout rate. The First Stage's time limit was increased to 120 seconds, and 150 seconds for female competitors.

While the time limit was very lenient, 11 competitors out of 50 survived the First Stage, and 10 out of the 11 competitors finished with more than 10 seconds left. Also, for the first time since SSAS 9, the First Stage spawn multiple clears with more than 30 seconds left.

The new Second Stage saw a complete renewal. Save for the Metal Spin and the Wall Lift where both of them served a modification, all others are brand new. The whole Second Stage course was reduced to only 6 obstacles instead of the previous 8 obstacles. The time limit was increased to 110 seconds, while 125 seconds for female competitors.

Despite the time limit was increased, the Second Stage was proven to be lethal in overall. While the new Cannon Shoot only directly took out one competitor, the new Salmon Ladder variant, Overdrive Salmon has been proven to be an issue. Despite the Overdrive Salmon only has one direct victim, the obstacle had spawned two competitors being disqualified under a hidden rule of the obstacle, the bar touched the top of the wall, failing to reach the final rung.

The new water obstacle, the Barrier Pool was the highlight of the course. It was proven to be a massive time waster. While the only direct victim of this obstacle was Karsten Williams, it did led few competitors to time out on later obstacles. Out of the 11 competitors who attempted the Second Stage, only one competitor cleared, Adam Rayl. In a post-run interview of Arthur, he stated that this tournament was the last time for his team, as they will took a break from competing and he "signed-off" with "we will be back, just don't know when".

Similar to the Second Stage, the new Third Stage was also completely renewed. The only retained obstacle was the Vertical Limit, which bring back the original version, Vertical Limit Tri, the rest of the course were all new. Rayl did defeat the first two obstacles, however ultimately fell at the third obstacle, the Jamming Logs, this ending the tournament.
