The lists below preserve those dates and their reported rewards; none confirms that the codes still redeem today.
What is MUGEN?
MUGEN is a Roblox combat experience by Pure Pure. The official Roblox listing describes it as fast-paced and shows the PC attack control as holding left-click/M1. Its current promotional description mentions a code, but that does not establish which codes were available in December 2025.

That report cautions against assuming these earlier codes stayed active through the end of the month.
December 21 snapshot

Digital Citizen reported these three codes on December 26. It named reward types but did not give quantities:

The December 26 report is also summarized by CloudsPress. These later codes should not be treated as a confirmation that the December 6 or December 21 codes remained redeemable.

How to redeem a MUGEN code
December guides describe this general process; the game interface may have changed since those reports.
- Open MUGEN on Roblox and go to the main menu.
- Select Codes. The December 21 guide places the button on the main menu.
- Enter the code exactly as shown, including its capitalization, then confirm redemption.
- If the reward does not appear right away, rejoin the game and check again, as suggested by the December 26 guide.
If a code does not work
- Check the date of the report. December lists were snapshots, and an older code may have expired or been replaced.
- Check spelling and capitalization. Enter the code exactly as displayed in its dated list.
- Leave Combat mode before trying again. The December 26 guide says codes should be entered when the character is not in Combat mode.
- Try rejoining. That guide recommends rejoining if a reward does not show immediately.
- Consider whether the code was already redeemed. Digital Citizen says each code can be redeemed once per account; this is third-party guidance, not a rule confirmed by the official listing.
What is confirmed—and what is not
The Roblox listing identifies the game and its basic PC attack control. The December code names, availability claims, reward amounts, and redemption guidance come from third-party articles. The official listing reviewed here does not independently verify those historical code reports, and there is no confirmed live status for them in this guide.
