Our independent guide dives deeper into DeadOS’s core systems, offering observations that help you fine‑tune scenarios without relying on hidden mechanics. By comparing settings and outcomes, you can craft outbreaks that match your creative vision while keeping performance stable.

01 / THE GUIDE

Assessing Scale Impact

Run two simulations: one with 5,000 humans and another with the maximum 25,000. Note differences in crowd movement, infection spread, and frame rates to understand how scale influences emergent behavior.

  • Start with a smaller population to gauge performance before scaling up.
  • Observe how crowd density influences infection speed.

02 / THE GUIDE

Speed Slider Exploration

Adjust zombie speed from the slowest to the fastest setting while keeping other variables constant. Observe how reaction time and survivor survival rates shift, highlighting the balance between challenge and realism.

  • Experiment with extreme zombie speeds to see how quickly the city collapses.
  • Adjust human accuracy to balance survivability against challenge.

03 / THE GUIDE

City Layout Experimentation

Design two contrasting city blocks—one dense with narrow alleys, another open with wide streets. Run identical outbreak parameters and compare infection pathways, noting how architecture guides zombie movement.

  • Use survivor control to test defensive positions.
  • Control an infected to explore how quickly they can spread the disease.

04 / THE GUIDE

Remote Control Perspective

Switch control between a survivor and an infected mid‑simulation. Record how each perspective reveals different strategic options, such as safe zones for survivors or optimal routes for infection spread.

  • Reduce simulation speed when testing complex city layouts.
  • Increase speed for quick outcome checks after parameter tweaks.

05 / THE GUIDE

Performance Tuning

Modify the simulation speed while monitoring system load. Identify the sweet spot where the simulation runs smoothly yet provides enough detail for analysis, especially when using the maximum population.

  • Enjoy the nostalgic look while focusing on simulation mechanics.
  • Compare visual clarity at different simulation speeds.
