2D platform shooter Cobalt will now launch in February 2016, publisher Mojang has announced.
The side-scrolling title is being developed by Swedish indie outfit Oxeye and published by the Minecraft maker.
It was previously announced for release this Friday, 30th October.
In a new post on Mojang blog, the studio admitted that Cobalt still had too many bugs to launch this side of Christmas.
"We've been working on Cobalt for a long time and, though the game is feature complete, our current build is buggier than we're comfortable with.
"We want every part of Cobalt - the campaign, challenges, and local and online multiplayer to live up to your expectations, no matter which platform you play it on. That's going to require a bit more development time."
Cobalt is currently headed to PC, Mac, Xbox 360 and Xbox One. Its console ports will be handled by Warhammer: End Times - Vermintide studio Fatshark.
"In honesty, we don't need four months to fix the outstanding issues, but releasing a game on console is an especially complicated business.
"There are release windows, and certification things, and all kinds of boxes that need to be ticked before games can be released into the wild."
