Thanks, hehe. Well I thought they're not really worth it. If you look closer into the stats of each DLC. Also the suits, not so cool as the ones you'll will get for free in the game (Advanced Elite Suit etc.). It's doable. Just take advantage of the many detailed guides on this very site. If ya need some more help just holla @ me.
Was good to see someone that did HardCore without any of the DLC packs. I'd been debating on whether I should or not, being that every walkthrough on here or TA has been "Get DLC" and goes from there. It gives me hope. Hah.
