Behind the scenes of Call of Duty map design: From concept sketches to playtesting strategies
The Creative Genesis: Sparking Map Concepts
Uncovering the origins of legendary Call of Duty maps reveals a fascinating creative process where initial concepts emerge through two distinct pathways. Infinity Ward’s developers shared their comprehensive approach to generating and refining multiplayer environments that have defined the franchise for decades.
The Call of Duty series has produced an astonishing legacy of multiplayer arenas, with over 500 original maps spanning 19 main titles and extensive DLC expansions. Each annual release typically introduces approximately 12 new environments, with post-launch content frequently doubling that number, ensuring designers maintain a relentless creative pace.
While not every creation achieves legendary status, the development methodology has consistently delivered genre-defining masterpieces that players remember for years. In an exclusive discussion, Multiplayer Design Directors Joseph Cecot and Geoff Smith detailed the systematic approach that transforms initial sparks of inspiration into fully-realized battlefields.
The creative ignition occurs through what Smith describes as a “chicken and egg” scenario. Some iconic locations emerge from meticulous research into real-world settings, while others begin as abstract gameplay layouts within the development engine, with thematic elements applied during later stages.
This flexible approach encourages constant creativity, with developers maintaining active idea backlogs regardless of their current project assignments. “We consistently encourage team members to sketch concepts,” Smith emphasized. “Even when focused on specific map development, we want them capturing new ideas as they emerge.”

The selection process prioritizes diversity, aiming to create what Smith compares to a “cast of characters” rather than similar layouts performing identical functions. Drawing from his Counter-Strike background, he notes how server rotation historically exposed players to varied experiences, creating natural pacing through different map intensities and styles.
Practical Tip: When conceptualizing your own map ideas, consider creating a “variety matrix” that ensures different gameplay experiences—close-quarters combat, long sightlines, verticality, and environmental hazards—to maintain engagement across your map collection.
Strategic Planning and Collaboration
Development synchronization between multiplayer and single-player teams represents a crucial early phase in each Call of Duty cycle. This cross-disciplinary coordination ensures thematic alignment while maximizing resource efficiency through shared location assets and design elements.
“During initial game development, we coordinate closely with the single-player team to understand narrative locations and settings,” Smith explained. “We maximize content sharing for efficiency while intentionally deviating from campaign areas to maintain gameplay variety.”
Following concept finalization, developers conduct extensive reference research to identify appropriate real-world analogues, particularly for larger maps. This involves analyzing infrastructure patterns, construction methodologies, and geographical layouts that can translate effectively into engaging gameplay spaces.
The technical implementation begins with blocking stages using basic geometric shapes—what developers colloquially refer to as “LEGO-looking” prototypes. Environment artists then join the process, suggesting structural adjustments and spatial relationships that enhance both aesthetics and gameplay flow.
Common Mistake: Many amateur designers overlook the importance of early cross-team collaboration, resulting in disjointed experiences between campaign and multiplayer modes. Professional studios prioritize this alignment from day one.
Beyond basic layout considerations, developers must account for numerous gameplay elements during this phase. Objective placements for various modes, spawn logic across different player counts, and even environmental factors like time of day require meticulous planning before artistic development advances significantly.
Environmental Design and Visibility
Environmental lighting and time-of-day selection represent critical design decisions that significantly impact gameplay experience. Recent graphical advancements have made these considerations increasingly important, as improper lighting can create visibility issues resembling constant flashbang effects.
“Overwhelmingly, bright daytime maps with clear skies prove most popular among players,” Smith observed. “This may reflect psychological preferences for cheerful, well-lit environments. We frequently utilize golden hour lighting since those sun angles showcase our visual fidelity exceptionally well.”
The development team maintains ongoing dialogue with environment artists regarding lighting placement, drawing inspiration from sports stadium design principles. “Similar to how stadiums orient playing fields to minimize direct sunlight in players’ eyes, we structure our maps to reduce obstructive glare during combat situations,” Smith elaborated.
Despite these efforts, lighting challenges persist, as certain angles inevitably create problematic visibility conditions. This constant balancing act between aesthetic appeal and functional gameplay defines much of the environmental design process.
Player “readability” remains paramount throughout development. Teams implement various techniques to enhance visibility, including background simplification to improve character silhouettes and strategic brightening of player models’ shoulders and heads to ensure distinction across all lighting scenarios.
“Ultimately, visibility and readability determine success,” Smith concluded. “While artists strive for cinematic beauty, our environments must function effectively as gameplay spaces first and visual showcases second.”
Optimization Tip: When testing map lighting, play from multiple spawn perspectives and during different in-game times to identify visibility issues that might disadvantage one team over another.
Rigorous Testing and Refinement
The transition from conceptual design to active playtesting marks perhaps the most intensive phase of map development. With numerous maps simultaneously in development and multiple game modes requiring optimization, testing represents both a critical and resource-intensive process.
“The perception of game developers playing all day doesn’t match reality,” Smith clarified. “While we dedicate significant time to playtesting—increasing to multiple hours daily approaching launch—we must balance this with other development responsibilities. Competition for testing resources among different map teams creates constant scheduling challenges.”
These sessions involve rigorous analysis rather than casual gameplay. Developers collect extensive feedback on sightline angles, spawn positioning relative to objectives, and occasionally identify needs for substantial architectural revisions requiring renewed collaboration with art teams.
To manage the overwhelming testing workload, developers have implemented innovative strategies. For expansive maps, teams isolate specific points of interest (POIs) and conduct focused Team Deathmatch tests within those confined areas. This approach provides more valuable data than hoping battle royale circles naturally conclude in targeted locations.
Game mode prioritization represents another key testing strategy. Given the impracticality of thoroughly evaluating every map across all available modes, developers focus on core gameplay experiences. “Search & Destroy and Domination require excellent performance,” Cecot stated. “More flexible modes like Team Deathmatch and Kill Confirmed can be optimized later, primarily through spawn adjustments.”
Smith reinforced this hierarchy: “We utilize TDM, S&D, and Domination as foundational testing modes. Other modes receive attention as resources permit, but ensuring quality across these three primary experiences remains our priority.”
The compressed development timelines inherent to annual franchise iterations often prevent comprehensive testing of every potential issue. Developers frequently face difficult choices between requesting artistic revisions after asset lockdown or implementing alternative solutions for identified problems.
“Neither scenario feels satisfactory,” Cecot admitted. “Requesting changes to finalized assets creates friction, while working around unresolved issues compromises quality. We continuously seek additional testing opportunities before release to minimize these compromises.”
This refined development methodology, though constantly evolving, has consistently delivered the iconic maps that define the Call of Duty experience. While some creations emerge through fortunate accidents and others target specific community segments, the structured yet adaptive process continues producing memorable battlefields that withstand the test of time.
Advanced Strategy: When playtesting, create a “issue severity matrix” that categorizes problems by impact on gameplay versus fix complexity, allowing efficient prioritization of development resources.
