Players can tackle the Mxyleprechauns mission to see if they can get a hold of some of Mister Mxyzptlk’s riches before time runs out. New this year are a pair of feats, a “Shamrock Strike Uplink Device,” and some additional decor for player bases.
The St. Patty’s Day Event has been running annually since 2011, and you can check out the wiki for a full rundown of its offerings. Good luck catching him and saving the city at the same time!
