Let it Die, a free-to-play game, has recently seen success on PlayStation 4. Developer Grasshopper Manufacture and Publisher GungHo Online Entertainment America recently announced that the free-to-play hack-and-slash title has passed 2 million downloads on PS4. The game came out on Dec. 3 in the United States and Europe and was recently released in Japan earlier this month.

The Japanese release has helped Let it Die reach the 2 million download milestone. On Jan. 4, it hit the 1 million benchmark. Let it Die is the first PlayStation 4 game for publisher GungHo which is best known for its biggest mobile game hit, Puzzle & Dragons.

Goichi Suda is the chief executive officer of Grasshopper Entertainment, the company that developed Let It Die. Suda is known for over-the-top, violent games like Lollipop Chainsaw and No More Heroes. GungHo is giving gamers a free Death Metal which is a premium in-game currency. Players who log into the game between Feb. 16 and Feb. 23 will get the premium currency which will allow players to continue the game after dying, as reported by VentureBeat.

Players who craft weapons during the promo period will also have rewards. Those who craft one weapon will get one day express pass x1, those who craft two weapons will get a four-leaf clover skill decal which has an increased critical rate by 10%. For those who create three weapons will receive a Death Metal.

The game Let It Die was first known as Lily Bergamo but at 2014’s E3, the game transformed into its current state. Let It Die is the first game that Suda developed since the studio was acquired by GungHo Online Entertainment. It is also the first PS4 game for both companies, as published by GameSpot.
