Part of the fun of playing Modern Warfare 2 lies in earning its unlockables — not just the weapons and equipment, but new titles and emblems, too. If you are looking for the most complete list on the Internet of the 594 possible titles and 294 emblems, we may have found it for you [via Call of Duty Wikia]:
The only action in the game that doesn’t seem to earn you a new title is dying repeatedly (sorry noobs!). Then again, this list isn’t complete — and won’t be for quite some time — so you never know. Thanks go to Adam Jorgensen for finding this list.
