Yak Scythe is a 2h melee override that was obtainable from the Summer Summit livestream event on 28 May 2016. The scythe was obtained by talking to Diango or Ianto about a scythe and entering the code 28052016 when prompted. The concept art was fan-made by player Legend Arts[1]. It was made unavailable after 4 June 2016.[2]
