Unlocking the Gold Retro Lancer for example needed about 100-200 kills. 100 kills with the Retro, and then another 100 with the Gold Retro once you unlocked it in the beta. Only that way would you get the GRL in the full game.
I didn't even play the beta and they gave me the gold lancer and gold hammerburst. wtf lol
[/quote]The Lancer and Hammerburst were part of an event where you would receive them just for playing a Versus game on release week. The Gold
Retro Lancer was achievable only through the beta (or Old Guard, technically speaking).
Make sure the "beta saved game" file is "In the same folder as "gears of war 3" saved game...In other words, open the Gow3 beta, go to saved game and move it to the gow3 saved game file...that should do it...
