Unlocking one of the hardest set of achievements in The Binding of Isaac will entitle players to a free copy of Polygod.
Polygod launched into Steam Early Access this week and is an FPS roguelike, with more than a few similarities to The Binding of Isaac. In order to drum up a strong base of early players, developers Amplify Games decided to give anyone who is really good at The Binding of Isaac a free copy.
In order to be eligible for the free copy players must have unlocked at least one of the following achievements in The Binding of Isaac: Hard Game, Eternal Satan, Eternal Cain, Eternal Isaac, Eternal ???, Eternal Maggy, Eternal Eve, Eternal Samson, Eternal Judas, Eternal God or Eternal Personalities. Those who have unlocked one or more of these achievements should send a message on Steam to the account Atomicdomb from the account that has unlocked the achievement.
"I really loved The Binding of Isaac and I think Polygod will resonate well with players that also really enjoyed The Binding of Isaac," said Dominic Obojkovits co-founder of Polygod developer Amplify Games. "Because of this, I want to reward the most dedicated players with a copy of Polygod."
