Which Biomes did you guys do the Untouchable trophy

if the power cut is frequent, then yes, it's advisable to use UPS. i haven't used UPS my entire life, nothing happened even when there was a period of cut off's. if u use low quality power supply, that is bound to cause an issue, same goes with motherboard.

Platinum done. Great game. But a lot more easier than Returnal. Not sure if it will have same replay value.
