While doing Terror Is Reality ranked matches you can win cash.
If you reach certain amount you can unlock them.
Then you can found them in the Safe House locker.


Champion Jacket
"The only TIR wear endorsed by Don and Paul!"

You can unlock this after winning a TIR ranked match.
Unlocking the Rising Star achievement should unlock this too.





TIR Helmet
"Reduces the chance of concussion by 8%"


You can unlock this by earning $1,000,000 through ranked matches.




TIR Uniform
"Complete with worn elbows and bloodstained knees"


You can unlock this by earning $5,000,000 through ranked matches.



Nowadays, you need to find/ask for people to play TIR matches and help you to get at least the TIR achievements.
You may know the game crash before the final results screen appears meaning you lose the cash you maneged to get in that match. You can avoid that if the host (or another player) disconnect on purpose. Doing this extend the matches you need to reach those millions.

With help of a mod you can unlock them but don't worry, after doing this you will have them as default, like if you did those TIR matches.

1. You need to download this datafile.big file. datafile TIR [drive.google.com]
   
   
2. Go to the game folder.
   Library -> Dead Rising 2 -> Manage -> Browse local files
   
   
3. Open the data folder. In there, you will found your datafile.big file. Make a backup of that file.
   
   
4. Decompress the datafile TIR.rar you downloaded before, you will have a new datafile.big file. Paste/move it inside the data folder. Replace if necessary.
   
   
5. Open the game, and load a game. Now inside the Safe House you will find these three boxes, those are the TIR unlockables.
   
   
   
6. Put on those three clothes. Go to the lockers and the TIR unlockables will be there.
   
   
   
7. Save the game (on another slot) and return to main menu.
   
   
8. You can start a new game or load a previous game (don't matter which) and the TIR unlockables will be inside the lockers.
   
   
9. Close the game, and return to the data folder.
   
   
10. Delete the datafile.big (the mod) and paste/move your original datafile.big file there.
    
    
11. And that's it, you have your original files and the TIR unlockables unlocked.

It's awarded for obtaining $10,000,000 in TIR after which it will become available at the Tinkerbox pawnshop, on Silver Strip, free of charge.



I couldn't find the way to unlock it the same way as the others. I also looked in the TIR related's files to find the value to change the cash we own (in TIR) but nothing.

It's temporary because you can only be able to use the TIR Moosehead as long you keep using the datafile.big that I edit (this "mod').

If you didn't unlocked the other TIR unlockables yet I recommend you to do it first (following the steps a write above, obviously) just to be sure you don't forget to keep them as yours.

If you already have the unlockables then you only need to download the datafile.big again (I already update the rar link) and put it in the same place (inside data folder).
Once you load in the game, go to the Safe House and you can find the TIR Moosehead next to one of the boxes:



The TIR Moosehead will respawn every time you go back to the Safe House, so don't worry if you broke it or leave it behind on one of your missions.

1. Using the "mod" shouldn't affect your gameplay if you keep it.
   
   
2. The "mod" only replace food items in the Break Room, and depending on the day some food may not be there. I didn't check it but this could affect only one of the TIR boxes.
   
   
3. You can equip the TIR Moosehead, save the game and return to your original datafile.big and still have the Moosehead on you but if you break it or leave it behind you will lose it. Yeah, i told you is temporary.

For those who came before, actually.

Honestly, I could made this "temporary" TIR Moosehead mod before but the point for this post/guide was to unlock the TIRs and keep it on your account permanently.
I didn't want to share just another game mod, you know what I mean?

I want to apologize to all of you who left a comment asking for it. Sorry!

Thanks to this thread [deadrising2mods.proboards.com] from Dead Rising 2 Mods I managed to make this "mod".
