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.
That's a truly staggering jump. Those new players won't necessarily stick around long-term, but if enough people have a good time with it then it could create an audience willing to sustain the game for months to come. Philippa said it had the "potential for a lighthearted murder merry-go-round", and she had a good time when she jumped in with the rest of the PCG UK team, so it's certainly worth at least trying out.
At the start of a round, you get assigned another player to assassinate, but you don't know their identity. Instead, you have to follow a "quarry compass" to get you in the right area and then watch other characters' behaviour, trying to spot a human player in a sea of NPCs. And, all the while, you have to watch your back to make sure you don't get stabbed.
The free-to-keep offer expires 10am PT on Monday. Grab it here—it's usually $20.
