I was curious, could you guys post up some of your used codes?
I wanted to examine them to see if there is a pattern, probably an
exercise in futility but I wanna see.

I'm referring to the 16 digit codes that you have to enter on the TF site to get
your DLC codes from them. You can post up your other codes too.

Please specify what character they're for if you don't mind.

 

I suspect this might get you in trouble. I can see this being similar to (though on a MUCH less scale) credit card fraud. Or maybe I'm being paranoid.

Here's Shockwave from GameStop:
SHFE-2NTQ-MMQ3-MTCX

And here's the 360 code that actually unlocked him:
VDC3K-2R9HJ-HVWPY-RKBH3-PVPVW

I would recomend converting them to their numeric values and such. I suspect that the codes have a sum value all the same and if you can figure that out then you should be able to reproduce them. Or maybe I'm grossly underestimating random key generation.

 

I had shockwave from Gamestop, too, and while I sadly don't have it written here with me, I do recall that it also started with SHFE. So there's part of your pattern.

 

It's okay, I've looked at many of them and they're random. No point in any further investment of time.
