5月14日にSteamで早期アクセスを開始した『Subnautica 2』が、発売後すぐに100万本以上のセールスを記録しました。本作は水中サバイバルゲームの続編で、リリース直後には同時接続プレイヤー数が46万7,000人に達し、1,000件を超えるレビューで「圧倒的に好評」という評価を得ています。
本作は、旧パブリッシャーであるKraftonとの法廷闘争を経て、開発元のUnknown Worldsからリリースされました。裁判資料によると、Kraftonのチャンハン・キムCEOは、ゲームの収益に連動する2億5,000万ドルのボーナス支払いを回避しようと、AIチャットボットを利用していたことが明らかになっています。3月には裁判所がUnknown Worldsの主張を支持する判決を下し、スタジオの管理権が回復されるとともに、ボーナスの支払い期限も延長されました。
X（旧Twitter）では、『Subnautica 2』が早期アクセス開始からわずか数時間で100万本を突破し、同時接続プレイヤー数が50万人近くに達したという爆発的なスタートが大きな話題となりました。ユーザーは本作の魅力を称賛する一方、舞台裏で起きたパブリッシャーとの騒動や、開発スタジオの回復力に注目する声も上がっています。
