I'm level 42 now on COD4, on my 5th prestige. Coincidently, on Hardcore Team Deathmatch earlier today, I got 42 kills on the Downpour level, which was pretty good. I also got the Red Tiger camouflage on that same level for the M4. Hardcore Search & Destroy gets you so many points, it's unbelievable. If you get around 3 kills each round, and it lasts for 4 rounds, depending on what level you are, you could get promoted. It'll net you around 1300 points. Alright, the amount of points you get is the same as the non-Hardcore version, but Hardcore is more realistic and more fun to play. More often that not though, you're thrown into a match when you're 0-3 down to the opposition, and with the score limit being 4 points, it's pretty much hopeless.
And yeah, the Home session with Mpilk and Ryan was alright, but you really need a keyboard for conversations, or even a mic. I was struggling re-arranging the furniture, blocking my route back into the house. It was fun. They really need to sort out the connection issues though, because it takes ages to log in.
