Middle-earth: Shadow of Mordor, the 2014 game from Monolith and Warner Bros. Games, is losing a few features on December 31st. The Nemesis Forge, Vendetta missions, and WBPlay stuff is going away, according to the publisher’s notice on the main Steam page. Nemesis Forge was the system that let players bring their named enemies from Shadow of Mordor into the 2017 sequel, Shadow of War. Vendetta missions gave players the chance to avenge online friends’ deaths by putting the baddies that killed them into other people’s games. WBPlay account linking offered players a couple of special runes, but the publisher will just give those to everyone in an update to make up for it.
None of the bits being removed are essential to enjoying the game. It’s likely most people would never notice anything missing if not for the official warning, so get out there and kill Snazgul Rathammer before time runs out.
