ok.... I messed up and got the anti tank mines instead of the life 2 thing. I reached rank 4 and used up all my unlocks. The next rank is 140 million XP and now I'll never get more credits to buy the life 2 thing. It's the thing that lets you inject your self.
 
Will deleting the demo and dowloading it again reset your stats? I really want the life 2 thing cause I keep dying without it. PS: The binoculars (sniper) ROCK!

I doubt if you redownload the demo it will refresh because youre username is already in the system so dont waste ur time doing it, but Support class heals you also so give that a try or if someone on your team is using the support class you automatically get healed when you stand near him

NO! I like the class with the grenade launcher and the assault rifles and stuff.  I'm already downloading

Um....deleting your game and redownloading it isn't going to affect your unlocks at all....obviously you're not really familiar with the way EA or DICE runs things, pertaining to Battlefield...

Um.

Support can heal himself and everyone else. Press R2 Button.

A lot of people don't know support can heal.

I know what you're saying, that was why the Life-2 thing was the first thing I unlocked with my credits, and I find that it's incredibly useful. It never runs out too, which gives you quite an advantage. It's saved my life way too many times for me to pick another class

As for the guys telling him to pick the support class, I think he's aware it can heal, he just prefers to use the assault rifles with undeslung grenade launchers, as I do.

Sorry, MP. You're going to have to make do with the anti-tank mines, I'm afraid. If you're really keen on the ability to heal though, you're better off just picking the Support class, it's not that bad.
