Hey so I have the DLC for the game (I had bought it years ago but only now returned to play it again), and I am wondering how to select all the DLC characters for any single player map, since they only appear when one of the main characters are unavailable. Do I have to play through the entire game again? Do I need to do a new game, or just replay every level again?

 

Also does it matter what my PSN account is when I play the game, or will I keep the DLC if I make a new one?

 

You can only play as certain characters on certain maps. There isn’t a way to play as all the characters on a single map.

And as long as you have the account you bought the DLC from on your PS3, every other account you create on your system will be able to use them.

 

Is there any way to get audio files or stuff like that from the DLC? I've always wanted to hear Jazz's lines and stuff in full

 

Hmm... you can try asking Barricade24 on YouTube, as I wouldn’t know. He has posted voice lines for several characters in some of his videos.

The problem is that he owns the PC version of the game and the DLC was never released on there. Only PS3 and Xbox 360.

 

Also the DLC was delisted after 2017, along with all Activision Transformers games.
But you can still download it digitally if you already purchased it.

 

Any idea how i could download it? I purchased it a few years ago

 

I don't have a PS3, so I have no idea how to go through the system's download history. I suggest you look it up.

 

If you go to the Playstation Store and then Downloads, you should be able to find all your purchased digital content there

 

I need some help figuring out how to attach the PS3 to the PC and get the files to my PC. I've looked it up and I can't seem to figure it out

 

When it comes to technicalities, I’m afraid this is where I cannot help you  

 

Yeah... that's impossible.
The game never had a DLC expansion on PC, and you can't transfer DLC from a console game to it's PC port.

 

I don't mean port the stuff to PC as in making them work on the game itself, i mean getting the files just, like, in a folder or something, with all the textures and music and models and stuff

 

I don't know how to go through the game's files. Maybe a cheating device or going through the game's folders.
On PS3 you could use something like nodding the console and going through the game's files. And on PC you could access the files more easily. I doubt the DLC will be buried in the PCs game's files cause it never had DLC on PC. Use the Cutting Room Floor, it's for going through video game files new and old. It might help.
