pops out?
So you've run the impulse application? (It'll ask to update once it connects, probably should let it)
Registered your game?
Still don't see the three versions on the my games tab list? (May only be one game that says Trinity I don't know since I don't have Trinity, only the pieces as they were released.)
Run any game updates listed there?
If that's the case, email [email protected] and explain your problem in detail. It's also helpful to include pictures of your game box and receipt so that they know you legitimately paid for it and you got the version you paid for.
Edit: You may have been ripped off by someone's carelessness in this case. Was the wrapper around the sleeve tampered with? It's probably best to take the game back to Target and explain to them what has happened and demand to exchange it for the proper game you paid for.
No Stant123, Trinity comes with all three in the package.
Everyone I've ever talked to about it said they got trinity and only the core game came in the box and they had to download the expansions just like the rest of us.
