StarCraft II fans around the world received a pleasant spring surprise, with news that GSL Code S would be continuing for its 16th consecutive year. While the tournament has been downsized once again—with the majority of the tournament now played online—the continuation of the storied GSL legacy was welcome news indeed.

The tournament retains its 12-player format from 2025, with two GSL-style group stages leading into a 4-player playoffs. Code S Season kicks off with Group A of the RO12, with Rogue, Percival, Zoun, and Solar looking to move on into the second group stage.



Group A is full of intrigue, with none of the four players standing out as a strong favorite. Rogue definitely has the most name recognition, but since his return from military service in 2024, his level of play has been wildly inconsistent. High marks included his runner-up finish in Code S Season 2 of 2025, and more recently, another second place finish in RSL Revival Season 4. However, he has also been knocked out frequently in the lower rounds of competitions, be it mid-size online events or last year's EWC.

The best versions of Rogue we've seen in his second act resemble his world champion peak, combining overwhelming macro play and cunning mind games unmatched by anyone else in the game. However, there's a marked inconsistency to his standard play that has held him back—especially when playing against top Protosses (well, that's a struggle for any Zerg these days). For example, actually beating MaxPax in the late-game during the group stages of RSL felt like it could be a turning point, but he ended up getting beat down 0-4 when they rematched in the grand finals. The best version of Rogue should get out of this group, but who knows whether that version of Rogue will even show up?

At least Rogue gets a soft initial opponent on paper in Percival, who was once a fringe Code S player who could only be given the "progamer" designation dubiously (albeit, it's been a very vague title for years now). However, he's now become the best StarCraft II story of 2026, rocketing up the Aligulac.com standings in the span of just a few months. While he's still only at 17th place at the moment, it's likely that doesn't reflect his true level as he's been putting up a competitive record against past Code S regulars. Some highlights from Percival's 2026 include several deep runs in weekly cups, victories against ByuN and Solar to qualify for GSL, and even a shocking upset against Serral to help his team win the WardiTV Teamleague (powered by a 3-base Marine-Tank all-in).

While there is an understandable, slight skew toward all-in strategies in Percival's play, he's also been quite impressive when playing standard as well. Typically, the best approach for GSL underdogs is to try and catch the favorites off-guard with a well-prepared cheese, but Percival could be justified in trying to take on his groupmates in straight-up duels. Moreover, the move to an online group stage format could help Percival as well, getting rid of the nervousness factor of playing on stage against vastly more experienced opponents.

It's hard to know where a fast-rising player will top out—post-military herO soared all the way to the summit, but we've also seen players like fellow groupmate Zoun stall-out just below the 'true' contender level. Wherever Percival ends up, it will be fascinating to continue following his StarCraft II journey through the rest of the year.

A few months ago, #1 Korean Zerg Solar would have been the lock-him-in favorite to advance from the group, but 2026 has not treated him kindly. The second half of 2025 saw him become the sole Zerg capable of challenging the mighty herO-MaxPax-Clem trinity in the weekly cups (a bellwether of good performances in larger events), but both his participation and results in such events have declined as of late.

It's hard to know what's going on with top-level players, now that the interval between major events has grown longer. It could very well be that Solar simply decided to take it easy for a while after the conclusion of the All-Star Invitational in January. His showings in the weekly cups right before GSL weren't inspiring, but he deserves some benefit of the doubt. However, if we believe that Code S is an entirely different kind of competition (and if you're reading a TL.net preview, you certainly do), then we should have some faith that a former champion will up his game.

Zoun. For a while, Zoun was almost like a Protoss version of Rogue, capable of beating championship-caliber players on his best days and falling apart on the off days. However, 2026 has seen him suffer a sustained slump, struggling to produce notable results in a variety of online events. The worst indictment of Zoun's current level is his path through the GSL qualifiers, where he barely made the final cut and took down some of the weakest participants in GuMiho, Ryung, and sOs.

Again, if we're to believe this diminished version of Code S still has a fundamentally different quality than every other tournament—whether it's due to the preparation time given for matches or the importance players place upon it—you can't write Zoun off. Perhaps the official return of the GSL gave him the vital dose of motivation to become one of the scene's most dangerous wild cards again. It may be grasping at straws, but his latest result does happen to be a 5-0 over ByuN in an iNu's Battles showmatch—here's to hoping that we see a locked-in Zoun compete.
