See the lovely figurines pictured to the right? Yes, those ones of Shepard, Grunt, Thane, and Tali from Mass Effect 3. Well, if you can afford them, then you'll also get DLC from the game. Yes, got the cash, then get the advantage!
Indeed, the lovely figurines, according to Bioware, "contain codes that can be redeemed for a downloadable content pack for Mass Effect 3 multi-player."
Okay, what do you get?
"(the codes) are slightly randomized during the registration and could include powerful new weapons and new characters. The pack could also include character boosters, weapon modifications, and weapon upgrades to make your multi-player squad stronger. (Only supported on XBox360 and PC.)"
How much?
"This is a pre-sale item with an estimated ship date of April/May 2012 Price: $75.00"
Yes indeed, if you've got $75 and can bear to tear the packaging open on the figurines, then you've paid your way to a DLC-based, multiplayer advantage, which isn't cheating at all, no way. In fact, other players will probably be pleased for you.
