- "If you're looking to get a headstart and unlock all of the Medal of Honor multiplayer weapons right away, this is your opportunity! We've released the Medal of Honor Multiplayer Shotcut Pack, which will allow you to get a Tier 1 arsenal from the start. To buy this pack, head to the in-game store and you can purchase it for 800 Microsoft Points. The pack will be available for the PlayStation 3 shortly.
The Front End will not update if you have unlocked the weapons with the kit shortcuts package. However, if you spawn into a multiplayer session, all weapons will be selectable from the spawn screen."

Ugh, why did they do that? Now all the nooblets will have the highest tier weapons.
