Building a first‑person sci‑fi shooter with Tesana

Tesana builder @jonesiller built a first-person sci-fi shooter with Tesana: a full arsenal, a squad at your side, tanks, mechs and a boss. Map I took 320 prompts.

“I wanted a shooter that feels huge: a whole canyon, a sky full of ships and a gate worth fighting for. Every few prompts it grew: a rifle, grenades, a squad, a third-person view, then tanks and a boss.”
@jonesiller · Creator of SOL: The Last Imperium

Big shooters usually take a studio. SOL: The Last Imperium started as one prompt on Tesana.

@jonesiller described the game they wanted: a first-person sci-fi shooter with a world worth looking at. Tesana built it, and every new prompt added more: a rifle, then a squad, then grenades, a third-person view, tanks and a boss. 320 prompts later, Map I was done.

It plays in a browser on any computer with a keyboard and mouse. No install: open the link and wait for the first load, about 350 MB.

The idea

A shooter with a world to look at

SOL is a first-person sci-fi shooter. Forty days ago the city of Corvina went silent, and the stone-born sealed the Shattered Gate in crystal. You join the Legion to take it back.

The canyon is the star. A beam of light cuts through the sky, a giant hangs over the horizon, a shattered moon drifts overhead and a capital ship blocks out the sun.

The sky over the canyon
The prompt that started it
Make a first-person sci-fi shooter for keyboard and mouse. You are a soldier of the Legion, sent with a small squad to retake the Shattered Gate, a huge alien gate sealed in crystal at the bottom of a red canyon. I want a world that looks epic: a beam of light in the sky, giant ships overhead, a shattered moon. Give me rifles, a pistol, a sniper rifle and grenades, a kick for close range, and let me switch to third person at any time.

The build

320 prompts to Map I

@jonesiller built SOL the way every Tesana game is built: by describing what they wanted and playing each new version a few minutes later. It went like this:

  1. StartThe first prompt
  2. 2 hoursPlayable
  3. 17 daysThe squad and the boss
  4. 5 NovMap I is out

Tesana wrote the code, built the 3D world and hosts the game. @jonesiller made the calls: what to add, what to change, what felt wrong.

The third-person view took one prompt:

@jonesiller's prompt
Let me press V to switch to third person at any time, with the camera over the shoulder, and keep everything else working the same.

What got built

Everything in Map I

Map I, The Shattered Gate, is one long fight down a canyon. Along the way it picked up:

  • An arsenal: the Sol Bolter rifle, a pistol, a sniper rifle and a thunder hammer you can throw.
  • Two kinds of grenade, Sunburst and Lightning. Hold G to aim, T to switch.
  • Third person, one key away.
  • A kick for anything that gets too close.
  • A squad: Sgt. Antonius, Stradia and X2‑Sol fight beside you and talk on the radio.
  • Wardens, drones and walking machines to fight.
  • Tanks and mechs on the canyon floor.
  • A boss, the Crystal Colossus.
