You asked for it. We will deliver. The first of many additions to come. Found over on the offical facebook page for the game, it looks like we will be seeing a hard mode and some new skins for free. It dosn't say when this content will be added however, but its good to see we are getting some free content instead of microtransactions and the bismal DLC missions.
True I can't see it being any harder, it was the same case with the DLC. Something they massivily overlooked is players at a high level being able to walk in there and complete the mission in just over a minute, they should add a level difficulty option and slam it on insane mode
I think Techland realize they made a mess of the DLC and so are compensating with this free content. Hopefully levels are nerfed on Hardcore.
