FNTD2 Tease – What’s Next?
At the end of the video, the developer hinted at FNTD2 (Five Nights TD 2) coming soon. With it, we can expect new admin codes and even more powerful units, possibly tied to the glitch theme.
Update 51 is one of the most generous patches for Five Nights TD in 2025. Between the glitched unit showcase and the long list of redeemable codes, players can stack up resources, test new strategies, and prepare for the eventual launch of FNTD2.
If you haven’t yet, redeem the codes as soon as possible before they expire and try out the glitch unit in your lineup.
