Why is this unavailable?

Imma be honest I haven’t played this in years just decided to download the game again after watching some Cynicalex vids on YouTube I forgot everything about this game there’s swords now, artifacts what not and whatever let me get straight to it why is this badass uniform unavailable? Cause I forgot they did stuff like this but can’t remember the reason, ready to buy it asap this is his coolest one yet design wise
