Infinity Ward’s Creative Strategist Robert Bowling has recently commented on the Killstreak system that Modern Warfare 3 will use.
When asked about the killstreaks which many saw as overpowered in MW2 bowling responded saying that they will be changed with a “COD4 mentality.”
He went on to add that the team will do this by making the air support only support to give the game a “gun on gun” focus.
