Biography

Cai “Summer” Yulun (born May 16, 1997, China) is a professional Counter-Strike 2 rifler currently competing for Rare Atom. Known for his veteran presence, consistent rifling output, and deep experience in Asian tournaments, Summer remains one of China’s most reliable and long-standing players.

Summer began his esports journey in the CS:GO era with a number of Chinese organizations including TYLOO, Flash, VG.Flash, and After. His competitive career spans more than a decade, during which he honed his mechanics, map knowledge and round control in the Chinese domestic scene. In late 2023 he joined Rare Atom, reinforcing the team with his experience and steady play.

On Rare Atom, Summer serves as a key rifler and in-game veteran anchor. His style is characterized by calm decision-making, smart positioning and a team-oriented mindset rather than pure fragging flashiness. In recent competitive samples, Summer recorded a Rating 3.0 of 1.02 across 60 maps, with a Firepower score of 48/100, Entrying 65/100, Trading 53/100, Opening 31/100 and Utility usage 91/100 — illustrating his role as a utility-focused support rifler. He has participated in five Majors, and although he has yet to lift a Major trophy, his experience and leadership make him a valuable roster member in Asia-Pacific competition.
