Phasmophobia: the investigation
Up to four of you enter a haunted location with equipment - a thermometer, a camera, a book the ghost might write in - and the job is to work out what kind of entity is there and get out. It is methodical. There are long stretches of nothing happening, which is precisely how the tension is built, and then something happens.
It rewards a group that will take it slightly seriously: dividing up equipment, reporting what they saw, agreeing a plan. A group that treats it as a laugh will find it slower than they hoped. Crossplay between PC and PlayStation, four players, and it is not usually stocked on Amazon so check the store price directly.
Lethal Company: the shift
Four of you land on a derelict moon, scavenge scrap to meet a quota set by an uninterested employer, and mostly die. The framing is corporate satire and the tone is comic, but the moment-to-moment experience is still four people alone in the dark making bad decisions.
It is looser and shorter per session than Phasmophobia, which makes it the easier one to fit into a normal evening - see our short sessions guide for why that matters more than most groups think. It is also the cheaper of the two. PC and Steam only, and not on Amazon, so check the Steam price.
Which one your group will actually enjoy
Pick Phasmophobia if your four want to be frightened, will co-operate on a task, and include someone on PlayStation.
Pick Lethal Company if your four are all on PC, want to laugh more than they want to be scared, and prefer shorter, messier sessions.
Pick neither if anyone is out on horror or cannot use a microphone.
What about three players, or five?
Both are built for four and both work with three, though a smaller group makes Phasmophobia noticeably harder and Lethal Company noticeably quieter. Neither takes five, which is worth knowing before you invite someone - our five-player page covers what does, and Dead by Daylight is the one horror game built for exactly five.
If you are a trio specifically, our three-player page lists games designed around that number rather than tolerating it.
The verdict
Phasmophobia is the better game for a group that wants horror, and the only one of the two a mixed PC-and-PlayStation group can play. Lethal Company is the better evening for four PC friends who want to laugh, and it is cheaper.
Decide by platform first, because that removes the choice for most groups, and by tone second. Both are on our horror roundup alongside the crossplay alternatives, and our Steam page covers the wider PC co-op catalog.
