You can grab all of Subnautica's achievements in 30 minutes using BiLLzuMaNaTi's guide By Sean Carey, 27 Jan 2020 CommentsThe survival sandbox Subnautica and the words "quick completion" are probably not a combination you'd consider putting in the same sentence. But thanks to a recently discovered in-game developer menu, all of Subnautica's achievements can be completed in about 30 minutes. The exploit discovered by EazyE2285, (who is currently writing a walkthrough for the game) involves using Freedom Mode, pausing the game and using both the right and left bumpers to open a developer menu. From there, you can enter several console commands that unlocks a bucket load of crafting materials, the ability to teleport and several other options. The exploit and exactly what you need to do to unlock every achievement has been made into a handy video guide (which we've embedded above) by TA regular BiLLzuMaNaTi. The video walks you through all of the things you need to craft, and tasks you need to complete to unlock Subnautica's 17 achievements worth 1000 Gamerscore. Previous estimates had the game down as a 40-50 hour completion, however various speedrun techniques and now the console command method easily gets Subnautica a sub-one-hour completion tag. BiLLzuMaNaTi also notes in the video that none of the achievements will pop until the end of the guide, so it's worth paying close attention in case you miss a step. If you're yet to check out Subnautica, it's a great game, and you may want to play it through instead of unlocking the achievements using console commands. The deep-sea survival title has a superb Metascore of 81, while here on TA, the community has given it a 3.84/5. It's also available to play via Xbox Game Pass, Xbox Game Pass for PC and xCloud.*EDIT* EazyE2285's Subnautica Walkthrough has now been published.
