Let It Die, the free-to-play PS4 action game, has racked up one million downloads in just over three weeks, developer Grasshopper Manufacture has announced.

"In just over three weeks, LET IT DIE hit a million downloads, and this number continues to grow each day!" reads a Facebook post.

Grasshopper is celebrating the milestone with a special in-game event, offering all players free Death Metals each day on January 6 to 8. An extra Death Metal will be given out for completing the naked challenge, as seen in the Twitch VOD here.

To be eligible for the reward you'll need to have already created an account and have space in your Reward Box.
