In response to overwhelming community feedback, Naughty Dog is experimenting with crushing-level difficulty in its Uncharted 2 multiplayer, and also offering a "plunder only" multiplayer playlist. Both experiments run for this weekend only.
For starters, ND says player health "in ALL game types" will be lowered to to 65 percent, the same as the Crushing setting, except boosters still are allowed. The "plunder-only" playlist also will be instituted for the same weekend. It runs from Friday at 10 a.m. U.S. Pacific time to Monday, Dec. 7 at 11 a.m.
More details are on the Naughty Dog blog. They definitely want your feedback, so go visit it to be heard.
