Classmate, I had the same problem as you before. I am also a wanderer under the stars, and I also reported the mistake of not finding the file. Later, I read several articles in the forum, and concluded that because the orc had to die two cracked versions, it was estimated that the patch given by the homeless children was not suitable for its previously released version of the game.

My solution is to download from 3DM, and their upgrade patch can be used for their own release. Orcs must die. And there are instructions on how to connect the cracked version on 3DM, of course, the online method is more troublesome.

As for how to use those new traps and new weapons, I suggest that I explore them myself, which is much more interesting than listening to others, and play a game alone and pursue my own unique style.

At the top of the 3DM Orcs Must Die Forum, there is an entrance link to download games and various patches, which is very convenient.
