After an extended European stay spanning most of the competitive year, Complexity Gaming achieved a remarkable 2-1 victory over Team Vitality in the BLAST Premier Spring grand finals. This triumph came despite suffering a devastating 14-round defeat in the opening map, showcasing incredible mental resilience from the North American squad.
What initially appeared to be a one-sided grand final quickly transformed into one of Counter-Strike’s most memorable comeback stories. The match dynamics shifted dramatically from Vitality’s early dominance to Complexity’s championship-clinching performance.
The North American organization made a strategic decision to remain in Europe as tournaments shifted from LAN to online formats, choosing to face stronger regional competition rather than return to their Dallas headquarters.
Vitality’s Vertigo Domination: A Tactical Breakdown
Team Vitality established immediate control on their Vertigo pick, demonstrating why this map remains their strongest competitive asset. The French squad opened with seven consecutive round victories on their terrorist side before Complexity managed to secure their initial round through bomb defusal.
Mathieu “ZywOo” Herbaut delivered an extraordinary individual performance on Vertigo, achieving a dominant 20-9 kill-death ratio with 112.2 average damage per round. His impact was particularly notable during a critical 3v5 situation where he secured round victory without his preferred AWP weapon.
The statistical standout emerged through the KAST metric (Kill, Assist, Survive, or Traded), where both ZywOo and Kévin “misutaaa” Rabier recorded identical 94.4% ratings. This exceptional performance level significantly exceeds the professional average of approximately 75%, establishing a new benchmark for the map.
Complexity’s in-game leader Benjamin “blameF” Bremer struggled to organize effective counter-terrorist setups against Vitality’s well-drilled executes.
Mirage: The Momentum Shift That Changed Everything
Complexity’s map selection of Mirage initially appeared to follow a similar pattern to Vertigo, with ZywOo continuing his individual dominance. However, the North American squad demonstrated improved coordination and strategic adaptation.
The match reached its dramatic peak when Vitality mounted a stunning six-round comeback streak, forcing overtime at 15-14. Complexity responded by winning all three counter-terrorist rounds in overtime plus the decisive terrorist round to claim victory at 19-16.
Will “RUSH” Wierzba, the ELEAGUE Boston Major champion, provided crucial stability as Complexity’s B site anchor, recording an 82.9% KAST rating.
The team victory showcased balanced contributions across all five players, with kill-death spreads remaining tightly clustered within seven points difference.
Nuke: Completing the Reverse Sweep
The final map began with intensity matching Mirage but concluded with the decisive authority reminiscent of Vertigo—this time favoring Complexity. The squad secured seven rounds on the traditionally challenging terrorist side of Nuke during the first half.
Benjamin “blameF” Bremer’s heroics became the focal point, including an anti-eco ace round and 101.6 ADR that led both teams.
The most critical factor in Complexity’s Nuke victory was their exceptional performance in clutch situations, winning four out of five such rounds. Valentin “poizon” Vasilev demonstrated remarkable composure during a first-half 1v2 scenario that shifted momentum decisively.
Complexity maintained their four-round winning streak through halftime before adding six consecutive rounds to complete the reverse sweep and claim the BLAST Premier championship.
Post-match celebrations captured by BLAST broadcast cameras revealed the dedication behind Complexity’s success. Auguste “Semmler” Massonnat directed coverage to blameF, who detailed their rigorous European training schedule.
“Every single day we implement three hours of new strategic developments…Our training commitment extends to six days weekly,” blameF explained following their championship victory.
Despite analytical predictions suggesting struggles against Europe’s stronger competition, Complexity established themselves as legitimate contenders within the regional scene.
Their upcoming competitive schedule includes the regional qualifier for Valve’s Regional Ranking tournament, CS Summit 6, facing Japaleno at 9:00 a.m. EDT on June 22.
