If you have all different letters, the decode key could be a possible 720 combinations. I've already solved the Control Room, and I'll tell you, it takes a long time to go through all the combos, even if you think you have the right password. You also need to know the password.
Sorry, it wasn't matchmaking, let me remember, i forgot. Search halo 3 rpg control room code and the second normal link is to a page in a forum, go to page 10 or 11 for the list. That's right, stouf has the full list on page two here. Sorry, forgot bio change, and games history and matchmaking have the same background.
Well you need to know the password to get pass the original Control Room, the Decoder Key, and the other password to use with the Decoder Key.
Which is what I meant, and I know this because I've already solved the Control Room. Decoder Key is by far the hardest part.
TurboGerbil-Nikheizen I'm good at head to head against guys my own level, but that's all I've really done.
I'm finding a bunch of guys around my level with like 0/85 W/L record, and holding over 1000 credits. I just feast on those guys.
Okage4 - Okage4 Um, the only tip I can really give that no one else has is to not even try and attack Donk Bot. Yes, he has a LOOOOOOT of money and makes the AI and attractive target, just don't even try. Donk Bot has never lost a match (since I last checked), and I'm fairly sure it's got stats that a skill level 50 should have or something.
