ActionTrip has posted up a preview of the upcoming Diablo II expansion, Lord of Destruction (though due to some copyright issues, this might not be the official name at release time). Here's a quick peek at one of the new foes that will be in the game:
Suicide Minions - The newest monsters created by Baal to serve in his army of Destruction, they are stealthy, quick-footed, and unusually tough for their size. Bony knobs protrude from their thick hides, giving them added protection against melee weapons. When ordered, they charge fanatically and die in enormous explosions.
