Welcome to Call of the Sea, a first person adventure puzzle game that has a similar feel to games like Myst and Riven, where you're pretty much on your own to figure out what to do, how to progress, etc. There is no HUD, no objective marker, no on-screen hints, etc. Just exploration and puzzle solving at its purest. That being said, with a guide to follow, there is essentially no difficulty to the game and it can be completed relatively quickly. However, the story is great to follow along with. If you want all of the achievements, you won't be able to just input the solutions to all puzzles, as you need to obtain all of the clues in your journal and interact with a bunch of stuff for achievements, so even the achievements essentially force you to actually play the game, it's just a matter of if you decide to solve the puzzles yourself or not. Let's get started.
Because this is an open puzzle adventure game, there are a couple ways you can use the guide below for the completion.
- Each of the achievements for completing the chapters in the game contains a walkthrough of that chapter that includes all story logs, journal notes, murals, miscellaneous achievements, and how to actually solve all of the puzzles. If you follow along with each of them you'll unlock all of the achievements in the game by the time you complete it, aside from Play it again, Norah (15G). This is the fastest way to complete the game.
- If you prefer to actually solve the puzzles and such yourself, and explore as much as you want, you could instead refer to each of the achievement solutions for the miscellaneous achievements to see where to get them, either as you go so you don't miss one, or to mop them up via chapter select after you beat the game.

If you follow along with the walkthrough in the achievement guide, you should unlock all achievements by the time you complete the game, aside from Play it again, Norah (15G). At this point you can simply load up a chapter via chapter select from the main menu to unlock it and finish off this completion.
If you missed any miscellaneous achievements, you can replay the chapter they're in from chapter select, quickly plow through the puzzles without interacting with notes and logs, to get them. If you're missing any collectibles, from the chapter select screen you can go to each chapter and see which ones aren't at 100% for story logs and notes, murals, and secret objects. Replay any levels you don't have at 100% and use the walkthrough in the guide to make sure you don't miss anything.
Call of the Sea is an awesome adventure puzzle game. The story starts a bit slow but really picks up and is engaging. The purist approach to the game and its puzzles is a welcome style after so many games with tutorials and hand-holding. Even without a guide it's not an overly difficult puzzle game, but one well worth experiencing for any fans of the genre out there.
