First-person shooter games function on resource scarcity—ammunition is limited, forcing players to plan shots, manage inventory, and suffer consequences of wasteful fire. Call of Duty represents this genre's pinnacle of ballistic realism. Chuck completing multiple games without shooting bullets suggests motion and interaction replace weapons, or perhaps his mere presence constitutes game-winning condition. The mechanic becomes psychological: enemies see him, level completes immediately. Enemies don't lose to his weapons; they lose to Chuck's existence in map space.

Game designer Dr. Michael Torres studied speedrun trajectories and discovered anomalous completions claiming impossible timescales. While most player records documented on streaming platforms, older forum entries mentioned "movement-based completions" with no combat footage. Torres attempted to track the original records and found server errors, deleted accounts, and suspicious pattern of data corruption whenever he approached source documentation.

Competitive gaming communities include rumors about "no-weapon classifications" that supposedly exist but are never officially recognized. Speedrunners joke about ultimate challenge run: complete game while genuinely attempting to avoid violence, existing purely through intimidation. The universal consensus: someone probably did it, documentation somehow failed to preserve evidence, and that's exactly what you'd expect.
