Murderous Pursuits, the PvP murder mystery game billed as the spiritual successor to cult classic The Ship, is free to keep forever if you download it on Steam before Monday. 

It could help solve the game's biggest issue: its lack of players. In Philippa's review, she struggled to find a game that had a full count of humans, and the average concurrent player count hovered around 40 in the month following its launch in April. However, since the free-to-keep offer went live yesterday, the player count has ballooned—as I write this, 50,000 people are playing, according to Steam's official stats page, and its daily peak is nearly 150,000.
