Arrowhead Game Studios is working on a big, free update to its Gauntlet reboot which will significantly improve the original release, the developer has said.

“In truth, we were never fully satisfied with how Gauntlet turned out,” Arrowhead’s game director Emil Englund said in a post to Arrowhead’s official site. “So, rather than just fixing little things here and there, we have been working on the core of the game to turn it into what we originally envisioned.”

Englund didn’t get into specifics, but said that the update will include improvements to the Campaign, Colosseum, as well as an entirely new game mode.

Gauntlet was originally released in September 2014. The game, which is a reboot of the 1985 original, got a fair score of 6/10 in GameSpot’s review. Earlier this year, Arrowhead released another top-down four-player cooperative game called Helldivers, which got a great score of 8/10 in GameSpot’s review.
