Moon Steps In for Xm at BLAST Slam VIII

Published September 29, 2026

Xtreme Gaming has named Kam “Moon” Boon Seng as its mid-lane stand-in for BLAST Slam VIII, replacing Guo “Xm” Hongcheng in the starting lineup. The club had initially selected Gao “Setsu” Zhenxiong for the vacancy, but a reported visa problem prevented that plan from going ahead. Moon was already registered as the sixth player, giving Xtreme a second option without changing the rest of its submitted squad.

The sequence is more important than the shorthand that Xtreme simply changed mid laners. Xm is the regular player who will miss the event, and the reviewed reports say the organisation did not explain his absence. Setsu was then identified as the intended replacement. Moon became the final choice after the visa issue, according to the report describing the second change.

Keeping those steps separate prevents two unsupported conclusions. Moon has not been announced as Xm’s permanent successor, and Setsu’s absence does not indicate that Xtreme rejected him for performance reasons. The available information concerns one tournament roster shaped by availability shortly before travel.

Xtreme keeps four established roles intact

The announced lineup places Wang “Ame” Chunyu at carry, Moon in the mid lane, Nicholas “zeal” Lim on off lane, Zhao “XinQ” Zixing as position four and Ye “BoBoKa” Zhibiao as position five. Wang “Maps” Yutian remains the coach. Only the second position changes in the starting five presented for BLAST.

That continuity gives Moon a defined structure to enter, but a mid-lane replacement still affects more than one lane. Hero priorities, rune movements and the division of farm between mid and carry can change with a different player’s habits. The sources confirm the personnel decision; they do not reveal whether Xtreme will redesign drafts or ask Moon to reproduce Xm’s usual responsibilities.

Moon brings substantial LAN experience. He is best known for his time with Mineski, including victories at PGL Open Bucharest and the Dota 2 Asia Championships 2018. He also played at The International in 2018 and 2019, with reported finishes in the 9th–12th range. More recently, he represented Yakult Brothers from December 2025 until June 2026.

Experience can reduce the adjustment cost of joining on short notice, especially when the replacement must absorb tournament routines quickly. It does not guarantee immediate synergy. Xtreme will still need clear calls around the middle lane and a draft pool that fits the five players actually attending rather than the lineup first expected.

A direct invitation with little margin

BLAST Slam VIII runs from September 29 to October 11 in Malta, with sixteen teams competing for $750 thousand. Xtreme received a direct invitation and was placed in Group A with PARIVISION, LGD Gaming and Level UP. That schedule turns the replacement from an administrative detail into an immediate competitive test.

Moon’s existing registration as the sixth player may simplify eligibility, but it does not create extra preparation days. The useful expectations are therefore limited. He is an experienced professional playing his natural position, four teammates remain in their listed roles, and the team has a confirmed group. Everything about form and chemistry must still be demonstrated in matches.

• Xm will miss BLAST Slam VIII for a reason Xtreme did not publicly specify.
• Setsu was the initial replacement before a reported visa problem blocked the plan.
• Moon was registered as Xtreme’s sixth player and will start in the mid lane.
• The remaining four player roles and the coaching position are unchanged in the announced roster.

Player	Tournament status	Confirmed context
Xm	Absent	The club did not state the reason
Setsu	Initial replacement	A reported visa issue prevented participation
Moon	Final mid-lane stand-in	Already registered as the sixth player

Xtreme Gaming has solved an immediate eligibility problem by moving from Setsu to Moon, an experienced mid player already included in its registration. The change preserves most of the lineup while leaving the central competitive question unanswered: how quickly can Moon fit the team’s drafts and map rhythm when BLAST Slam VIII begins?
