Lady Love Dies can bring the accused to trial at any time, but it’s generally more effective to explore the 24th iteration of the island to gather as much evidence as possible and talk to everyone who may have valuable information to share. There is much more to this mystery than the mass murder of the entire Syndicate Council, but anyone who takes it on can expect plenty of humor and quirkiness.

The planets are constantly changing over each 22-minute cycle, meaning that players will need to visit and revisit certain locations in different runs beforeor after specific events occur, helping to discover invaluable information (the only carry-over from cycle to cycle). Staying alive is itself something of a challenge, since oxygen is a limited resource, space is full of volatile locations, and miscalculations of trajectory can see the spaceship fly off into the abyss.

The deep lore and satisfying combat make the Horizon series a must-play for any fans of interesting scifi stories — don't skip the audio logs in this one!

begins with player-character Harry du Bois waking up with drug and alcohol-induced amnesia. Playing more like a tabletop RPG than a traditional role-playing game, Harry and his colleague Kim Kitsuragi are detectives tasked with solving a murder in the world of Elysium, which has over 6000 years of complicated history.
