Here is some scary info about CODMW2
There will really be customizable kill streaks. You can choose which kill streaks you want now so instead of having your kill streak at 3, 5, and 7 you can do 3, 4, 5 which seems to be what most people love. *Note: you can still only have 3 kill streaks at a time. You can stack these kill streaks? Unlike Call of Duty 4, if you’re in heated combat and get your 3rd, 4th, and 5th kill streak all at once, you will still be able to use all three. This way, it doesn’t skip over to your most current.
There are death streaks. Death streaks are new to Call of Duty: Modern Warfare 2. If you are in a match where you happen to die a certain amount of times in a row, your death streak will activate for a limited amount of time during your next life. For instance, if my death streak was Copycat and I died 3 straight times, for a limited time during my 4th life I will get to copy the load out of the last person the killed me.
They are making it even easier to get kills, dumbing it down and dumbing it down. At some point in the COD Series you will just have to sit back and watch your character kill everone in the match like an action movie.
I may just be the last thing you see before you re-spawn!
