The latest playlist in Left 4 Dead 2's mutation mode breaks out the katanas - "Four Swordsmen of the Apocalypse" is easy to figure out from the title alone: swords only, versus the horde.

The Left 4 Dead blog says the mode pits survivors against "near continuous streams of Special Infected ready to be sliced and diced." And look, it still cuts a tomato like this!

The update teases next week's change - something called "Hard Eight." Is that a spiteful response to the last poll, which found the Hard Rain boat wait as the least favorite finale of the game? Who knows.
