Subnautica is a survival game on an alien ocean planet. It starts calm with exploration and resource gathering but quickly gets more intense the deeper you go. The world is immersive and the amazing music really adds to the atmosphere and tension. It can feel a bit slow at times but the exploration, mystery and overall vibe make it really worth playing. 🎚️ Difficulty 🔲 My grandmother could play it 🔲 Easy 🔲 Normal ☑️ Hard (It is hard until you understand it.) 🔲 A challenge to be reckoned 🔲 In the heat of confrontation, (Only PVP games) 🗺️ Graphics 🔲 MS Paint 🔲 Bad 🔲 Meh 🔲 Normal 🔲 Very Good 🔲 An original artistic direction ☑️ Beautiful 🔲 Masterpiece 📚 Story 🔲 This game has no story 🔲 Basic element of the contractual requirements 🔲 It's there for people who want it 🔲 Well written ☑️ Leading to more in-depth researches/thoughts 🔲 A model to get inspired by ⌛️ Length 🔲 0 (No story) 🔲 Short ☑️ Average 🔲 Long 🔲 To infinity and beyond 🎶 Music 🔲 Just filling noises/No music 🔲 Trivial and uneventful ☑️ Good and/or fitting the game's artistic dispositions 🔲 Memorable 🔲 Transcending whispers of a forgotten world 🕹️ Interest 🔲 I would rather watch paint dry 🔲 Hard to enjoy 🔲 Repetitive and/or uninspired ☑️ A good moment 🔲 Sticking out of the pack 🔲 You will remember it long after 🔁 Replayability ☑️ A one-time experience ☑️ For achievements 🔲 If you wait a few months/years (or with mods) 🔲 Definitely 🔲 Infinitely replayable (or almost) 🐛 Bugs ☑️ Never heard of 🔲 Minor bugs 🔲 Can get annoying 🔲 Impacts the player's experience badly 🔲 The game itself is a big terrarium for bugs ⚙️ Requirements 🔲 You can run it on a microwave 🔲 Low ☑️ Average(ish) 🔲 High 🔲 NASA computer 💰 Price 🔲 Free 🔲 Underpriced ☑️ Perfect Price 🔲 Could be cheaper 🔲 Overpriced 🔲 Complete waste of money 🤑 Worth Buying 🔲 No 🔲 If you have nothing else to play 🔲 Wait for sale ☑️ Yes 🎯 Expectations 🔲 It's a completely different game 🔲 This game is a scam 🔲 It's missing many features they announced ☑️ Looks very similar to the steam page 🔲 Better than expected and/or announced 🔲 Masterpiece, no patch or feature has to be added. ✒️ Final Rating 🔲 1 🔲 2 🔲 3 🔲 4 🔲 5 🔲 6 🔲 7 ☑️ 8+ 🔲 9 🔲 10 Thank you for taking the time to read and think about this review.
I was fortunate enough to go into this game blind, knowing nothing about it. And in the spirit of keeping this review vague so others may experience what I did, all I will say is that this game is one of a kind. I yearn for games like this set in alien oceans. The base building in this game is simple and fairly enjoyable, and this is from someone who dislikes base building in pretty much any game. Exploration is integral and rewarding, as you get to learn more about the world you are in and all accompanying mysteries. That being said, resource hunting can be a chore early on, and still a chore but to a lesser degree in the latter half of the game, but if you can endure it, you are in for a great time. Mechanics aside, the story is alright, there isn't anything novel. You learn a lot of what happened on the planet from the logs scattered around the world, which gives yet another reason for continuing to explore the world. Story also feels like it wasn't getting enough attention past the 75% mark, so it felt like there was more that could've been done with it. Overall, this game is one of those rare 10/10's that if you are fortunate to go into blind, will be a hell of a ride, and seeing as this game goes on sale often enough, I recommend buying it at that time
great game, i love how its so beginner friendly as you can find loot caches at the back of the large spaceship and at the very edge of the maps. If you are having trouble progressing just go in a random direction until it says you have entered the ecological death zone (this means that there are no dangerous creatures) and there you will eventually find an upgrade for your system which will begin to leave tips for further progression into the game. Goodluck! <3
Pros: + Sounds and music are outstanding + Great design of flora and fauna, absolutely gorgeous game world with data entries explaining life on the planet. + Simple crafting system and easy to use. + Exploration of the unknown is top notch + Ambience and atmosphere is crazy awesome + Doesn't hold your hand. You gotta find out yourself what you have to do. + All the vehicles are just so much fun in their own way and customisable! + Base building is the greatest + Ranges from fun tropical paradise, through mysterious and alien, to murky horror. + Lots of tools at your disposal with different purposes. + Really good story despite a silent protagonist and lack of characters and dialogue. + A huge ocean to explore. With the right gear and sub you can go pretty deep. + So many small details and things to discover that aren't necessary to the game but are simply awesome. + Modding support Cons: - Some resources are damn hard to find. - Single save slot for a game - I think a craftable tool to allow for mapping out your surroundings for reference would have helped greatly rather than relying on memory and beacons constantly for waypoints. - no multiplayer or co-op - The primary weakness of the game is that the magic of the first playthrough fades, as most of the games charm comes from the fear of the unknown. This makes replayability somewhat worse than expected. - Lack of minimap (there is a mod for that) Recommended start : do not read any guidelines, go in as blind as you can get Happy diving!
