Explore the mysteries of the biolab!

This epic survival game finds you and your raft alone on an ocean full of dangers and mysteries. Your only objective is to survive, but remember – there are more dangerous things than thirst and hunger at sea! Collect resources, build your raft, research and craft items, explore islands and fight for your life. Don’t let your guard down – zombies, sharks, mutant crabs and other enemies will do their best to put an end your adventure!


First things first: find water and food to stay alive. It isn’t as simple as getting them from the ocean – you’ll have to find a way to collect water and cook food.

Build your raft, collect resources from the ocean and islands, craft vital items and equipment using the advanced crafting system and find unique recipes on islands. Become a real survivor!

The weather is both your friend and your enemy. Try to adapt to different weather conditions and see how they influence characters.

World map. The ocean is huge! Start off your adventure by exploring islands and all the mysteries and dangers they hide. Every island has its own story to tell to those who listen...

Danger is everywhere. Fight for your life against sharks, zombies, mutant crabs and many other threats. Zombie sharks never miss the scent of blood...

Balance changes needed

Hello, I have been playing this game since its launch, and I recall there used to be many more crafting recipes, armor and weapons, etc. Currently in the game there are quite few items that doesn’t have a corresponding crafting recipe, such as: Shark meat. Also some other items depend heavily upon random loot drops that logically should have their own crafting systems. Such as: Acid (Jellyfish and sulfur perhaps), Gears (Metal alloy or ball bearings).
Some other problems involve high crafting costs of materials, such as metal pipes, while the requirement of one metal sheet is quite reasonable, the need of 25 processed planks seems to be a lot too much. And the recipe of pipe gun should be reasonably using regular metal bars too.
Some other balances needed are the stats of certain weapons, such as bows and clubs, alongside the butcher knife, these weapons delivers much weaker blows to enemies compared to their much easier to craft counterparts like spears.
The trader appears only once a day for 20mins only, the time seems to be quite short, and the required items for trade is way to randomized and unpredictable, perhaps adding more single item trading options with cheaper prices compared to boxes.
Keep up the good work! If you’re reading this, thank you for your time as well.

The game is actually pretty good, some ideas..

This game is one of the only survival games on ios which are actually pretty in depth with some of the things you can do, on top of being a raft game. I don’t really have any complaints, besides one which is that searching corpses shouldn’t really take energy away if I’m being honest. Some ideas I thought about was it would be cool if there was multiplayer, or adding a trading system across players so we can create a community within the game, maybe make a bed like item where we can have a faster generation for energy when we go offline or are afk on our raft, creating bigger backpack spaces because there is a lot of loot on the islands and it’s very unenjoyable to have to go back and forth multiple to get all of it. Maybe a portable kind of boat where you can go around and collect things in the water (this would be able to be destroyed by shark to make it balanced) and in some type of way make a class selection kind of thing, for example ( medic/ receives more healing from medical items) (survivor/ bows-melee weapons do 10% more damage) (soldier/ guns have 5% further range) things like that could make the game feel more personal. And the final thing could be a more in depth character creation screen, maybe different skin colors, long hair/ short hair, eye color, etc. anyways, thank you for reading my rating and I hope to see this game improve much more in the future

Developer Response ,

Hi! Thank you for such kind words. We are not planning to add multiplayer to the game yet, but maybe we will in the future. Soon we will add event islands to the game and change the storyline. You will have interesting adventures! Also you will be able to create rubber boots, because without them it will be very difficult to pass the Waste Island. We hope you enjoy this adventure. 😏 the rest of the offerings look interesting, we'll be sure to check them out! We are very pleased that you play our game! ♥️

Great game but a few bugs

I’ve been playing this game for a couple days now and I’ve come to really enjoy it. I love the concept and the different survival elements. However I have noticed a couple things that may need to be fixed. First off, I was never able to find an electric lock pick and seeing as you can’t craft one I was wondering if this may be a bug? Same issue with fuel for the abandoned transport on some island. I wasn’t able to find any. Lastly the parts for the engine on the raft are extremely hard to come by. You can supposedly get them from only one of the islands you have access to without it and after 4 days I have yet to get even one of many of the parts. When searching drawers and toolboxes on the island you get more of the common parts that can be found anywhere else. I feel as though these place should produce more parts for the engine. I’ve killed the mechanic four times now and he’s the only thing that has given me parts for it. Lastly, I have been able to complete the task “kill 10 mutacrab” even though I’ve killed probably 30 since it started. It still says Ive completed 0/10 of the task. Besides these issues, this is a really great game and I can’t wait to see what it becomes!

Developer Response ,

Hi! Everything you described is meant to be added to the game later. Soon we will be releasing a new update that will change almost the entire game. There will be new quests, history, new interface. I think you will really like it :)

Ah yes, crabs. You have to kill them on the island of bones.
