10 Rarest PS4 Trophies

Kill-Netic is an achievement that will remain in the rarest category likely forever now, given that Orcs Must Die! Unchained is currently offline and unplayable unless you find an offline single player launcher.

Even when it was online, though, it wasn't exactly a walk in the park to land yourself this particular trophy. In order to get it, you'd need to use Gabriella's kinetic pulse ability to kill thirty enemies in a single second - which is pretty clearly difficult, even when read by those who have never played the game or indeed the series.

The main issue around this is that it requires crowd control, but not by wiping out enemies. You can't let your foes go past you - because you need them to stack in one area to take them out effectively - but you also can't have them killed by traps because you need the numbers.

Given the attack fires in a cone as well, this meant you had to have a fair few enemies set up in a relatively small space, making it all too clear why many never got the trophy, and now maybe never will.
