If you somehow missed playing Borderlands 2 or Borderlands The Pre-Sequel or simply don't own them on PC yet you are in luck as they are both free on the Epic Store.

Borderlands 2 is one of the best looter shooters and the Pre-Sequel is well worth checking out and now that they are free it's even better.
