Cobwebs is a 3--5 player conspiracy horror trpg about a single character investigating the disappearance of a loved one.
The PDF is 72 pages, with easy to read text and excellent low-fi, zine-style art and layout.
Cobwebs is played with d6s, a d12, tokens, a playmat, and optionally a voice-recording device. There's a Twin Peaks-y vibe to its setting, but its malleable enough that you can use it to run games in the present day or the distant past as long as you preserve the general atmosphere of suspense, distrust, and alienation in a crowd.
Because your main character is played by the group, character creation takes a different approach than many other systems. You're encouraged to leave chunks of your protagonist undefined and find out who they are during play.
Also, since there's no fixed GM, the group generates core plot hooks before beginning play.
In essence, uncertainty is your GM, and as you play elements of the story will naturally snap into place.
To support this approach, the game uses Theories and Motifs to keep everything loosely connected. Theories are each player's best guess at what's actually going on. They're kept secret from other players, but they are explicitly used to guide narrative decision-making. Motifs, meanwhile, are public knowledge and have no meaning on their own, but everyone is encouraged to include them. A Motif might be an image, or a song, or a reference, and everyone is encouraged to sneak it into scenes.
That said, Cobwebs *is* still a game that can be won and lost---at least by the main character. The game's playmat tracks time, danger, suspicion of NPCs, and other elements in a very corkboard-y kind of way. If too much time is elapsed, or too much danger accumulates, the story ends---sometimes abruptly and unhappily.
An unhappy ending to the story isn't necessarily an unhappy ending for the players, though. Cobwebs is a game that you play to enjoy the act of playing it. You play towards drama, and suspicion, and towards confirming your theories about the plot. Sometimes that means you get an ending like Alan Wake, and sometimes it means an ending like Blair Witch.
For player resources, multiple safety tools are provided (X-Card, Lines & Veils.) There are also game sections on modifying Cobwebs to support more players, to allow multiple main characters, and to resolve at-the-table conflict. A bunch of scenario hooks are included for groups that want to jumpstart their investigations, and the hooks are varied and compelling to read. Random tables are also provided to quickly generate names, relationships, fears, objects, and more, and finally the book features a list of media touchstones in case you want some Mars Volta or Alice Isn't Dead to get you into the right headspace for Cobwebs.
Overall, if you enjoy trpgs as a chance to act, and theorize, and engage socially, Cobwebs should be on your radar. And if you specifically like stories like Stranger Things or Twin Peaks, it should be towards the top of your list. It's not a crunchy game, and it divides up player agency in interesting ways, so it's best played with a group of friends that wants to collaborate, and who don't mind if they lose as long as the story is good.
