Is it possible to easliely create new entities in Half-Life, i dont mind if its difficult because this would be really useful? (I dont mind about scripting/coding if thats required because i can give that a shoot) by new entities i mean like in Azure Sheep they have the special forces soldiers and the normal soldiers. Example: In my mod i would like Russian Soldiers, in Russian colours and American soldiers, in their colours to fight against each other (Like the Special Forces and the Soldiers in Azure Sheep).
Sorry if this isnt clear, just tell me if it isnt and ill try and make it simpler.
Thanks!
