Flowing liquid-like enemies, digital creeping enemies, and custom scripted opponents are a few of the challenges that face players in this genre-altering expansion to the Creeper World series. Creeper World 3 once again shocks strategy gaming by refining and significantly expanding the core game play of the prior highly successful Creeper World titles.

Players engage a compelling story across countless missions fighting back a fluid enemy that literally flows over the dynamic terrain. Players employ terraforming tools, advanced weapons, orbital drops, and other devices as they engage on variable size and shape maps.

Also featuring a full map editor with support for advanced scripting, players are armed with the tools to create an infinite variety of user generated content. Maps can be shared on-line and include game play that spans casual to serious.
