Speaking on Infinity Ward's forums, communications chap Rob Bowling has confirmed that Trophies aren't going to be added to the PS3 version of Call of Duty 4.
"At this time, we have no plans to patch in Trophy support for Call of Duty 4: Modern Warfare for the PS3," he said. "Much like DualShock rumble addition to the PS3, the support for these new features have come much to late for us to add it to Call of Duty 4: Modern Warfare due to our current production schedule."
There are currently about 3,000 "game x won't have Trophies" stories doing the rounds, but we thought we'd let you know about this one. Because it's a big game you may care about.
