If you want to replace the cutscenes in Battle Bears Zombies, here’s how.
In order to edit these cut-scenes, first you need to access them from in game.
To do this, you need to follow this directory on File Explorer:
C: -> Program Files (x86) -> Steam -> steamapps -> common -> BATTLE BEARS 1 ZOMBIES -> BB Zombies -> BB ZOMBIES_Data -> StreamingAssets.
In the StreamingAssets folder, there should be twenty .m4v files. These are the cutscenes for the game, and you can view them using your media player of choice.
(I would recommend you copy these into a backup folder for safe-keeping in case you need the original cutscenes.)
Done all that? Good. Let’s get some files so we can replace these.
For this step, take your cutscene that you want to replace, and make note of its name, you will need this for later.
Now, take the video you want to replace the cutscene with (length is irrelevant) and make sure its file extension is .m4v.
If it is not a .m4v file, change the extension to .m4v (from testing, this method appears to work with .mp4 videos).
Now you are all set to replace this cutscene, let’s do that.
Find the cutscene you wish to replace, and copy its name over to its replacement, and add another character/space so that no messages will pop up.
Next, move/delete the original cutscene so that its replacement is left in the StreamingAssets folder, and rename the replacement so its name is identical to that of the original cutscene.
Now there is one thing left to do, on to the next part.
The only way to do this (as of 7/18/21) is to play through the game like normal until you get to the part with the replacement cutscene. Watch and enjoy.
If it does not work, look back over the parts presented to be sure you did not miss anything.
