Case Study

Prosocial Voice in Call of Duty®: Warzone™

Abstract
In Call of Duty®: Warzone™, teams are at their best when players work together. This correlational case study explores how prosocial voice interactions appear in live Call of Duty®: Warzone™ matches and how they align with player experience.

Findings indicate that prosocial voice interactions are observable at meaningful scale and extend beyond a small subset of highly engaged players. Exposure exceeds active participation, reflecting a one-to-many dynamic in which team-supportive voice reaches a broad in-match audience.

Prosocial voice frequently appears during high-coordination moments of play, often alongside cooperative gameplay actions such as revives and thanks events. Sessions containing prosocial voice are directionally associated with stronger same-session continuation signals, suggesting that healthy social interactions align with short-term session momentum.

This analysis highlights the importance of understanding and amplifying constructive social dynamics that already exist within competitive environments. Healthy communities are not defined only by reducing harm, but also by recognizing and strengthening prosocial player behavior.

Understanding positive social interactions is important for both community health and for sustaining engaging player experiences within competitive environments.

Executive Summary

This case study examines prosocial voice interactions in Call of Duty®: Warzone™ (North America, December 4, 2025 - February, 4, 2026) and provides a directional view into how positive, team-supportive communication appears in live gameplay.

Prosocial voice interactions are identified using Modulate's ToxMod voice analysis solution, enabling aggregated analysis of how these behaviors appear in live gameplay environments.

The analysis shows that prosocial voice interactions are observable at meaningful scale, with a substantial portion of players exposed to positive communication during matches. Exposure consistently exceeds active participation, reflecting a one-to-many dynamic where constructive interactions reach a broad in-match audience.

Prosocial voice interactions frequently appear in high-coordination gameplay moments and are commonly observed alongside cooperative actions such as revives and thanks events. These patterns suggest that positive communication tends to cluster when teamwork and coordination are most critical.

Sessions containing prosocial voice interactions also show directionally stronger same-session continuation signals compared to other cohorts. This is interpreted as a short-term session momentum signal and does not establish a causal relationship.

Taken together, these findings highlight that positive player interactions are already present at scale within competitive gameplay environments. Understanding these interactions is important for both community health and for sustaining engaging player experiences. While much of the industry focuses on reducing disruptive behavior, this additional layer of analysis underscores the importance of recognizing and reinforcing positive player behavior.

1. Introduction: Why Positive Play Matters

Call of Duty® is at its best when players work together. In fast-paced, competitive environments, communication helps support how players coordinate, work together, and experience the game.

Industry discussions around player behavior have largely focused on identifying and reducing disruptive behavior. While this work remains critical, the understanding of how positive, team-supportive interactions appear within live gameplay environments warrants additional focus.

This case study explores how prosocial voice interactions — communication that supports teamwork and constructive play — appear in Call of Duty®: Warzone™, and how they align with player behavior during real matches.

The goal is to better understand how positive interactions show up at scale, where they tend to occur, and how they relate to short-term player experience signals.

2. What is Prosocial Behavior in Call of Duty®: Warzone™?

Prosocial behavior in Call of Duty®: Warzone™ refers to actions or interactions that benefit other players or contribute to a positive gameplay environment. It is not the absence of disruptive behavior, but the added presence of actions that support teamwork, coordination, and constructive interaction.

Examples of prosocial behavior include:

Prosocial behavior can appear across gameplay actions, voice or text communication, and broader systems that reinforce positive interactions. It reflects moments where players contribute to making the game better for others.

2.1 What this Case Study Measures: Prosocial Voice

This case study focuses specifically on prosocial voice interactions observed in live Call of Duty®: Warzone™ matches using Modulate’s ToxMod solution, aligned with Activision’s definition of prosocial behavior.

Prosocial voice interactions are defined as team-supportive communication captured through voice transcripts and categorized into three categories:

While prosocial behavior can appear across gameplay, communication, and systems, this case study focuses specifically on prosocial voice interactions observed during Call of Duty®: Warzone™ matches.

Voice interactions are classified into these categories and reported at an aggregated level. The analysis is designed to identify broad behavioral patterns and does not evaluate individual players.

2.2 Methodology

This analysis focuses on Call of Duty®: Warzone™ gameplay sessions in North America between December 4, 2025 - February 4, 2026 (Season 01 and Season 01 Reloaded).

Key characteristics of the analysis:

  • Prosocial voice interactions are identified through Modulate’s ToxMod solution, as aligned with Activision’s definition of prosocial behavior.
  • Results are aggregated at cohort level (e.g., exposed players, speakers).
  • Metrics are interpreted directionally and do not establish causal relationships.
  • Findings reflect the specific time period and game environment analyzed above.
  • Findings are aggregated and interpreted directionally, and do not establish causal relationships.

3. Key Findings

  • Prosocial voice interactions are observable at meaningful scale in Call of Duty®: Warzone™ matches.
  • Exposure to prosocial voice extends beyond the subset of players who actively speak.
  • Prosocial voice frequently appears in collaborative gameplay moments.
  • Sessions containing prosocial voice show directionally stronger same-session continuation signals.

4. Scale: How Often Prosocial Voice Appears

Prosocial voice interactions are present across the Call of Duty®: Warzone™ player population and are observable at measurable scale.

During the analysis window:

This reflects an approximate 1:4 speaker-to-exposed dynamic, where one prosocial speaker reaches multiple other players in a match.

At the match level, approximately 2.5% of Call of Duty®: Warzone™ matches contained at least one prosocial voice interaction.

These findings indicate that prosocial voice interactions are not isolated events, but appear consistently across live gameplay.

5. Reach Across Player Cohorts

Beyond scale, understanding where prosocial voice appears provides additional insight into how players interact during gameplay.

Prosocial voice interactions are not confined to a small subset of highly engaged players - they are observed across active, new, and returning players alike.

Across active, new, and returning players:

These patterns suggest that prosocial voice interactions extend across a broad audience within the player base.

6. Prosocial Voice in Collaborative Gameplay

Prosocial voice interactions appear across core Call of Duty®: Warzone™ game modes.

Analysis of game mode distribution shows:

  • Prosocial voice occurs across both core and limited-time Call of Duty®: Warzone™ game modes.
  • Certain team-based modes show higher per-match rates of prosocial voice. These modes emphasize squad coordination and collaboration rather than solo play. This reflects observed patterns in where prosocial voice appears and does not attribute specific causes for these behaviors.
  • The majority of prosocial voice exposure still occurs within high-volume core Call of Duty®: Warzone™ game modes due to overall match scale.

These findings indicate that prosocial voice interactions are present across broader Call of Duty®: Warzone™ gameplay, with higher concentration in game modes that emphasize teamwork and coordination.

Prosocial voice interactions also frequently appear alongside cooperative gameplay actions.

Analysis of matches containing prosocial voice shows that approximately 66% of prosocial voice matches also include at least one cooperative gameplay signal, such as reviving or thanking another player.

These cooperative actions represent moments where players actively support one another in gameplay.

The observed co-occurrence suggests that prosocial voice interactions often appear during high-coordination moments, where teamwork and communication are most important.

7. Session Momentum and Player Engagement

In addition to where prosocial voice appears, we examined how it aligns with short-term player behavior within a session.

Prosocial voice interactions are directionally associated with stronger same-session continuation signals.

Analysis of matches containing prosocial voice shows:

This comparison reflects how often players continue playing additional matches within the same session after encountering a prosocial voice interaction.

These findings suggest that sessions containing prosocial voice interactions are associated with stronger short-term session continuation signals. This is interpreted as a directional observation and does not establish a causal relationship between prosocial voice interactions and player engagement. It should not be interpreted as long-term retention impact.

8. What this Means for Positive Play

Taken together, these findings provide a directional view into how prosocial voice appears in live gameplay and how it aligns with player experience. Positive, team-supportive communication is already observable on a meaningful scale within Call of Duty®: Warzone™.

Prosocial voice interactions:

  • Appear across a broad player population, extending beyond highly engaged groups.
  • Occur most often during collaborative, high-coordination gameplay moments.
  • Are directionally associated with stronger same-session continuation signals.

These patterns suggest that positive social interactions are closely tied to how players experience teamwork and communication within competitive matches.

Healthy communities are not defined only by reducing disruptive behavior, but by also recognizing and strengthening constructive player interactions that contribute to positive gameplay experiences.

As the industry continues to focus on mitigating disruptive behavior, understanding and reinforcing positive interactions will be equally important in shaping the future of online communities.
