Hier nochmal ein guter Kommentar ausm Steam Forum : Getting No Mercy AND the survivors from Left 4 Dead 1 is going to murder the fanbase for L4D1. As the only reason to play Left 4 Dead 1 for most people are the campaigns and characters. L4D1 is losing them and not getting the Left 4 Dead 2 characters or maps in exchange. It's a lose lose deal for Left 4 Dead fans but a win win for Left 4 Dead 2 owners.
Würden sie die DLC nur für Besitzer von L4D1 + L4D2 für L4D2 rausbringen würde niemand "meckern".
