Dirty Bomb scripts compression.

Post by Gazyi »

Hello. I'm interested to dig in Dirty Bomb Unrealscripts, but .u files have custom compression that doesn't supported by UEdecompress. I heard some people decompressed them. Samples are here: https://www.mediafire.com/folder/tcvxyc ... ed_scripts

Dirty Bomb .u Decryption | UE3

Post by nevecex »

Dirty Bomb ( https://store.steampowered.com/app/333930/Dirty_Bomb/ )

I have a problem with extracting some meshes and textures from the game. Using UModel and decompress.exe from gildor I manage to get a big chunk of game models and textures, but a few of textures and models seem to be in the file ShooterGame.u and it seems encrypted. Decompressor fails on this file and I have no idea how to properly decrypt this so I'm looking for your help. If anyone skilled can provide me with a tool, script or a guide how to decrypt this file I would be thankful. I uploaded the ShooterGame file and a few smaller .u files just in case. If you need anything else uploaded from the game ask.

Thank you.

You have already opened the same topic few months ago.
Now I have merged all of them in an old topic of 2016 but if nobody replied for 2 years it's difficult someone will now.
