- This is the first of hopefully several scripts that create and manage Half-Life monsters so they can be spawned and messed with in several mods.
- This script cannot be used as a plugin by itself. You can spawn headcrabs with the simple test plugin that is also attached.
- This script has built in natives, check out the test plugin to see how simple it is to make a plugin with this script. (Test plugin command: spawn_headcrab)
