In the story-driven, co-operative adventure game LA-1, you take on the role of detectives working for Mace Doyle Investigations who are helping one another to resolve cases in the post-apocalyptic city that was once Los Angeles. Each case can be played individually or as part of a campaign. Because of the multiple cards that can send investigations in different directions, it's possible to play each case more than one time, having different situations and outcomes each time. But cases must be solved before the Darkness closes in on all the investigators.
