Doom

You’ve played Doom Eternal. You love Doom Eternal. And so going back to 1993 sounds like archaeology — a grey-brown corridor sim your dad played on a machine that whistled when it dialed the internet. I understand the instinct. Most old games deserve that instinct.

This one doesn’t. Doom has never been bettered at the one thing it does, and Eternal — as much as I love it — is a game built around the absence of this thing.

Here’s what you’re walking into: no upgrades. No skill tree. No resource loop. No armour pieces to grind. You have a shotgun, eventually a rocket launcher, and a set number of health points that only go up when you find health or kill things smartly. That’s the entire economy. And the moment you start moving, you understand why that matters — because every single mechanic in Doom is in service of velocity. You don’t reload. You don’t aim down sights. You hold forward, you strafe, and you fly through levels at a speed no modern shooter allows because modern shooters are terrified you’ll notice their levels are small.

And the levels are the actual argument. John Romero and Sandy Petersen built these maps like puzzles that fight back — keycard hunts that loop back on themselves, rooms that change when you return to them, monster closets that are funny the fourth time and still tense the fortieth. The level design is legible in a way nothing since has been. Every encounter is placed. Every secret is authored — and hunting them is a game in itself, one the game never explains, because 1993 Doom shipped with a manual and an attitude.

There’s a cynical-mechanics story here too, which you’ll enjoy: Doom’s shareware model meant the first episode was free and spread by floppy disk through every office and university in the western world. It became a productivity crisis, a legal debate, and the foundation of an entire studio’s empire — because the game itself was so good it functioned as its own marketing. The mechanics were the business model.

What will actually get you, though, is the feel. Doom is where FPS movement was invented, and the strange truth is that it was nearly solved on the first attempt. The strafe, the momentum, the rhythm of shooting then dodging then shooting — Eternal’s whole combat loop is this DNA with thirty years of systems bolted on. Go back to the source and you find the purest version of it. A half-hour of E1M1 and your hands relearn what your brain forgot: that a shooter can be a flow state, not a build.

It’s cheap. It’s on everything. There is no version of your setup that can’t run it. You’ve killed the Icon of Sin twice — go meet his grandad.

Play this one anyway.
