I read the negative comments saying that you should play Green hell instead, that this game is bad, etc... However, I decided to buy it anyway! Let me tell you this: Project Castaway is one awesome survival game, yes it has similarities to green hell; so if you like green hell, you are going to love Project Castaway too! The survival in Project Castaway is easy in comparison to green hell, even though the survival mechanics are similar. The building mechanics in project castaway are better because you can move around your placed items and change them from one place to another. Project castaway is for people who love the island survival theme; Green hell is for people who love the jungle survival theme. Project Castaway has better graphics, better building mechanics and better book guide! Project Castaway is for all those who got bored of playing green hell. If you have survived the jungle in green hell, then give this game a chance and survive now on a tropical island! Don't listen to the bad reviews! If you do, then you are going to miss the opportunity of playing an awesome survival game taking place on an island!

Singleplayer, offline. I do not understand why all the bad reviews. It is a charming and beautifully made game. It is not a huge game but more than fair value for its price range and certainly a bargain on sale. I enjoyed the about 40 hours content. It was never very challenging, and resources were abundant but the journey was enjoyable and entertaining. I had a few crashes but just reloaded the last save and carried on. I can find fault easily but none of it will affect the outcome of this review. I built a small base but mostly operated off my large raft with storage, bed, barrel stove, cover and water gatherer as "home". I hunted sharks and treasures. Dived deep to collect packages and built the escape. A solid 6.5 to 7 out of 10 game, fair value for money. Recommended.

First what I don't like. I don't like that they do Not tell you what you have to do / make Before you can save your game. I wasted so much time and energy having to re-start all over again and again because I was exploring and gathering items. I did not know you had to make a base and then a bed Before you could save. They don't tell you that part ! That NEEDS to be stated in the game ! Before anyone gets mad about me saying this , I am 63 and did not grow up with all this teck. I do like the game . I love to build and gather. I am hoping they add more islands to it. There is not enough to explore ! LOL I would like to see more stuff to build. Thank you.

Not gonna lie, I was invested... 43 hours in just to realize that the "Quests" don't Activate in Coop. No Bottle Notes, No Sticky Notes, No Quest Completion. Kind of Annoying. The game is fun, I mean I made it 40+ hours Scavenging, Building, Exploring before I even realized "Where the Hell are all the Notes?". I only bought this game with intentions to complete it with my Girlfriend (we loved Green Hell and Stranded Deep). This game is neither of those two games... a few similarities but GH and SD are still both better games, this game missed the Mark. Like I said, it is fun. I am just salty about the Quest Line issue, I can handle the Bugs. I won't give it a Bad Review but it did Piss Me Off.

I really like this game. Your plane crashes and you swim to the nearby island. You have to find something to eat, make a shelter, keep warm, don't get sunburned....all typical survival type stuff. And with the newest update, you do have the choice to choose the "conditions" off or on (like sunburn, cold, parasites, etc). You can also choose the difficulty level and the passage of time (very slow, slow, normal, fast) There are wild animals you need to contend with, also. You make weapons and tools. mine for minerals, gather herbs, make bandages, etc. The story line is great, too. There are multiple islands you can explore after you build your raft. You have to find various notes and blueprints that are scattered all over the islands to eventually escape. I've been playing for a while, through various updates and it just keeps getting better and better. But keep in mind that it is still in the Early Access stage and there are some glitches here and there. There is a Discord page that you can access and the Devs are great at listening to suggestions. I hope you will enjoy it!
