The catalog in 3D
The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.
How it feels
a tense co-op descent where every deeper dive tempts greed against dwindling safety.

What players say
Players praise the devs for rapid patching and frequent improvements, but one reviewer reports dying constantly from a lack of oxygen. The co-op loop is compared to Sea of Thieves underwater, and some enjoy breaking out of bounds in the hub.
