Batman: Arkham Knight returned to PC this week, but players continued to report problems. Now, Warner Bros. has announced an unconditional refund program for people who want their money back.

"We are very sorry that many of our customers continue to be unhappy with the PC version of Batman: Arkham Knight," the developer wrote today on the game's Steam page. "We worked hard to get the game to live up to the standard you deserve but understand that many of you are still experiencing issues."

So until the end of 2015, Warner Bros. will offer full refunds of Arkham Knight "regardless of how long you have played the product." In addition, players can get get their money back if they bought the DLC pass, but only if they return it along with the full game.

For everyone else, Warner Bros. said it plans to "continue to address the issues that we can fix and talk to you about the issues that we cannot fix."

The Warner Bros. post also includes an update from Valve that says the refund process, like the game itself, is experiencing some issues.

"For users still running into playtime based refund rejections, we are looking into what is causing those. Please wait to re-submit your refund until we have this resolved. Thank you," it said.

Arkham Knight originally launched for PC alongside the PlayStation 4 and Xbox One editions in June. However, the game was later pulled due to bugs and other issues. It officially returned on October 28 with a package of free games given to players in an attempt to make up for the issues.
