Think you’re good? Left 4 Dead 2 to have ‘Realism’ mode

Hey, I hear you’re pretty good at killing zombies in Left 4 Dead. Getting on the rescue chopper? Too easy. And that boat? That Tank may as well take his lunch break, because he’s wasting his time, right? 

Well, the “Realism” mode — a game modifier spotted by 1UP during a recent Left 4 Dead 2 demo — is about to test your skills. While Valve isn’t ready to reveal the mode in full just yet (it was apparently a modifier it forgot to hide for the press demos), marketing director Doug Lombardi dropped a few hints on the mode apparently designed with the “hardcore” player in mind.
“Take Portal for example,” he says. “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 of more. Realism is for those players.”
How exactly it will affect game play is unknown. One could guess that we’re talking less health, or maybe headshot-only zombie kills. What would you like to see applied to Left 4 Dead 2‘s “Realism” mode?
