Steam News announces the release of a new automatic patch for Left 4 Dead 2, fixing Russian localization strings in the zombie shooter sequel, while also adding the new Iron Man mutation. The Left 4 Dead Blog has details on the new mutation, saying: "No respawns, no restarts, no ammo, all tension! Did you vote the Mutations are too easy? Try this one on Expert. Realism rules are in effect. There are no respawns in the map. There is no ammo. If your team wipes, you need to restart the whole campaign."
