I will add that the game was made on the engine: Unreal Engine 3
Could you provide some more details on what exactly you are attempting to do?
I would like to translate the game into Polish.
I translated almost all the dialogues, but I can’t add to the game Polish characters: A, C, E, L, N, O, S, Z, Z.
It better is you ask about this in the UDK (UE3) subforum:
Or talk to the developers, you can’t edit built games using UDK or the UE4 editor. These forums are for games built from scratch rather than editing commercial games.
