Headshot %
27.7%Killjoy
27.0%Iso
Killjoy lands headshots at a slightly higher rate (27.7% vs 27.0%), providing a modest but meaningful advantage in time-to-kill during duels.

Attack Side Breakdown

Killjoy demonstrates a modest attack-side advantage over Iso in this matchup, converting 39.0% of attacking rounds versus 37.5%. While this 1.5 point edge gives Killjoy slightly better site-taking capability, the gap remains narrow enough that skilled Iso players can overcome it through superior execution and team play.

The data from 4 competitive games suggests Killjoy's kit provides marginally better tools for attack-side scenarios. This could manifest as slightly more effective entry utility, better post-plant stalling, or superior mid-round adaptability. However, Iso teams shouldn't dramatically alter their attacking approach — instead, focus on tightening execute timing, coordinating utility chains more precisely, and ensuring trades are happening when entries fail. Small improvements in team coordination can easily overcome a 1.5% gap.

When taking entry duels, Killjoy holds a slight statistical advantage but nothing that should change fundamental approach. Iso players should still take confident entries when they have good information or utility support. The key adjustment is ensuring you're not taking unnecessary 50-50 duels — look for angles where you have an advantage through utility, information, or teammate support. Killjoy can play slightly more aggressively on entries, knowing the statistics marginally favor them.

In post-plant situations, Killjoy's slight advantage likely stems from better utility for denying defuses or controlling retake angles. Iso should compensate by being more deliberate about post-plant positioning — take spots that offer escape routes or trade potential rather than hero plays. Stack post-plants with teammates when possible, and use utility efficiently to maximize delay time. The 1.5 point gap can be neutralized through smart post-plant fundamentals.

Defense Side Breakdown

Killjoy shows slightly better defensive capabilities than Iso, winning 62.5% of defense rounds compared to 61.0%. This 1.5 percentage point edge suggests Killjoy's kit provides marginally better tools for CT-side play, though the gap remains small enough for skilled Iso players to overcome.

When deciding site assignments, Killjoy can slightly more confidently take solo anchor roles. Their 1.5% defensive advantage likely stems from better stalling utility, superior information gathering, or more effective site-holding positions. Iso should consider pairing with a teammate on their site rather than solo anchoring, or taking positions that allow early rotates rather than committing to extended holds. The advantage is small but worth considering in close games.

Killjoy demonstrates marginally better retake capability in this matchup. Whether through superior clearing utility, better post-plant positioning, or stronger clutch mechanics, Killjoy converts retakes at a slightly higher rate. Iso should focus on retaking with numbers — don't take hero 1v1 retakes against Killjoy when you can wait for teammates. Killjoy can be slightly more confident in isolated retake situations, knowing the statistics marginally favor them.

On eco and force buy rounds, the 1.5% gap becomes more pronounced as utility advantages compound. Iso should be more conservative with eco aggression against Killjoy and prioritize saving for full buys where team utility can compensate for individual disadvantages. Killjoy can play slightly more aggressively on force buys, knowing their defensive kit provides small but meaningful advantages even with limited economy.

Overall Side Analysis

Killjoy holds clear advantages on both attack (39.0%) and defense (62.5%), establishing themselves as the superior choice in the Killjoy vs Iso matchup regardless of map side. This consistency across both halves means Killjoy doesn't need to play for specific sides or rely on winning a particular half to succeed.

Killjoy's advantage holds across all map types and team compositions. Whether on attack-sided, defense-sided, or balanced maps, Killjoy performs better. Iso teams should consider compositions that can cover their weaknesses — pair Iso with strong fragging agents who can carry during their difficult matchup encounters, and ensure utility supports Iso's positioning.

For ranked climbing specifically, Killjoy is the objectively better pick in this matchup. If you're equally comfortable on both agents and frequently face this matchup, practicing Killjoy provides a measurable ranked advantage. Iso players should focus on team play, utility value, and avoiding direct Killjoy confrontations rather than trying to outfrag them.

The verdict is clear: Killjoy wins this matchup on both sides of the map. The combined 3.0 percentage point advantage across attack and defense represents a meaningful statistical edge. Iso isn't unplayable, but faces an uphill battle requiring stronger team support and more disciplined play to compete.

Sentinel vs Duelist Dynamics

The Sentinel (Killjoy) vs Duelist (Iso) dynamic creates asymmetric encounters where each agent brings fundamentally different tools to engagements. Killjoy's Sentinel abilities serve different purposes than Iso's Duelist kit, meaning direct fights often feature non-equivalent utility exchanges.

Understanding how Sentinel abilities interact with Duelist counterplay is essential for maximizing your agent's potential. Killjoy's Sentinel toolkit may excel at certain aspects while Iso's Duelist kit counters others. The Killjoy advantage suggests their role's capabilities translate better to winning these cross-role encounters on average.
