i thought COD4 was great. onlin3e play is really good. the hardcore mode makes play as it should be, a couple of bullets and you are down thinking where did that come from?
go into a server with 55 people for team death match, get the 5 kill streak and then count the kills from the carpet bombing. ill give people a tip, if you do this, dont call the heli afterwards straight away. wait until you next die and then call it in. then that way you and the heli will cap off enough quickly up to that 5 kill streak for another carpet bombing. then rinse and repeat your kill:death ratio will rocket
