There's a Left 4 Dead 2 Preview on 1UP.com with another look at the just-announced Scavenge mode for the multiplayer shooter. At the end of the article they mention a menu option called "Realism Mode," which Valve's Chet Faliszek said was "a special modifier that we forgot to hide for this demo." They asked Doug Lombardi about this, explained this was for super hardcore players, saying: "Take Portal for example: We had our best internal players who could blow through that game in about 30 minutes, but within weeks of launching it we had people on YouTube beating [the testers'] times by 10 minutes or more. Realism is for those players." Thanks VG247.
