Getting Started

.entities Files

Levels are edited through ".entities" files and are saved in:
<resource>/maps/game/<campaign>/<level_name>/<level_name>.entities

Example:
e1m1_intro_patch1/maps/game/sp/e1m1_intro/e1m1_intro.entities
Would be the level file for Hell on Earth.

Remember to check for the highest resource load priority for the level
