About Creeper World 3: Arc Eternal
Creeper World 3: Arc Eternal replaces traditional combat units with a fluid‑like “creeper” that spreads across terraformable terrain. Players must adapt bases, weapons, and strategies to this continuously moving threat, which behaves predictably yet offers surprising tactical depth.
User‑generated content is central: a built‑in map editor, the Dial Map Device for sharing worlds, and a CRPL scripting language for custom enemies, weapons, and effects. An active online community supplies thousands of maps, while the story arc delivers unique foes across many star systems.
01 / THE GUIDE
Thermodynamic Fluid Physics
Creeper spreads like a fluid, governed by thermodynamic principles rather than discrete units. This creates a continuously evolving threat that reacts to terrain changes and player fortifications.
Because the fluid obeys predictable rules, elevation, containment structures, and timing become key tactical considerations, making each encounter dynamically different despite the underlying consistency.
- Watch low‑lying areas where creeper pools before expanding upward.
- Use raised terrain to create natural barriers that slow the spread.
02 / THE GUIDE
Built‑in Map Editor
The editor lets players design worlds of any size, dimension, or shape. Created maps can be uploaded to an online database for sharing with the community.
All built‑in story missions were originally crafted with this editor, demonstrating its capability to produce complex scenarios without external tools.
- Start with a small test map to learn the editor’s tools.
- Export the map address to share and receive community feedback.
03 / THE GUIDE
Dial Map Device (DMD)
The DMD allows players to dial up worlds by adjusting dozens of constraints, then share the resulting address online. This enables rapid prototyping of mission parameters.
Players can exchange DMD addresses to experience each other's custom scenarios without downloading separate files.
- Experiment with extreme constraint values to discover unexpected layouts.
- Save favorite DMD addresses for quick access to preferred challenges.
04 / THE GUIDE
CRPL Scripting Language
Creeper World 3 exposes hundreds of engine commands through its CRPL scripting language, enabling custom enemies, weapons, and effects. Community examples illustrate its versatility.
Even the official story missions were scripted with CRPL, showing that narrative and gameplay elements can be authored by players.
- Review forum examples before writing your own scripts.
- Test scripts in a sandbox map to avoid unintended behavior.
05 / THE GUIDE
Prospector Star‑System Exploration
Prospector missions let players explore hundreds of star systems containing thousands of worlds. These missions expand the game beyond the core story.
The variety of system sizes and mission lengths—from five minutes to five days—demonstrates the simulation’s scalability.
- Prioritize worlds with abundant resources for long‑term survival.
- Terraform early to secure higher ground in a new system.
