Netmarble unveiled key systems and a demo build of its new roguelite action RPG, \'Solo Leveling: Karma\', at Tokyo Game Show 2026. The company held a media presentation on Sept. 17 at Makuhari Messe in Japan, with executives from Netmarble Japan and Netmarble Neo in attendance. The demo includes more than 200 buffs, 8 playable characters and a controllable Shadow Army. Pre-registration began on Sept. 16 in Korea and Japan.

As development costs rise and hits become harder to predict, South Korean game companies are turning to proven intellectual property to reduce release risk. Rather than building new worlds and characters from scratch, they are adapting web novels and webtoons that already have readers and fandoms to secure early users and ease marketing burdens. Nexon, Netmarble and Kakao Games are preparing new titles based on such IP, though the industry says strong execution still determines success.
