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, claustrophobic retro shooter where you navigate a drifting spaceship amid an alien threat, relying on careful inventory management.

What players say
Players praise this as a faithful revival of the obscure Zero Tolerance, capturing its tough but fair challenge with autosaves and no save scumming. The atmosphere and soundtrack stand out, though some note jank like enemies shooting from outside render distance and rare softlocks.
