Water Landing is a Cast Away scenario in the style of Subnautica.
It's 20 pages, with a solid, thematically appropriate layout. The text is easy to read, and the background is a blue gradient that grows darker the deeper you scroll---a really nice flourish.
Water Landing adds new mechanics to Cast Away's core, but Cast Away is not a hard system at all to learn, so Water Landing takes it up to about medium complexity. The added mechanics include a card grid gameboard, randomized card-based events, craftable items, and optional traitors.
Water Landing meshes extremely well with Cast Away's open-ended-but-still-survival-oriented approach, and it integrates time-tracking, conditions, and other Cast Away elements with ease. The writing and table entries are also strong throughout, and Water Landing does a good job of balancing the group's descriptive freedom against a clear sense of the game's environment and the things that inhabit it.
Overall, I would strongly recommend Cast Away to most groups, and I would strongly recommend Water Landing to most groups with Cast Away. If you like Subnautica, or if you simply like open-ended survival and exploration scenarios, water worlds, or cooperative-competitive team gameplay with crafting and lots of optional mechanics, I'd highly recommend giving this a try.
Minor Issues:
-Pages 9-11, random letters are bolded throughout the tables
