From the first commit to today.

First version: one web page that generates a mountain landscape you can look around in 3D.

The code was split into modules with automated tests. A default world builds its rivers and lakes in 74 ms and its towns in 64 ms.

A night look: the survey area glows over mountains drawn as dotted contour lines, with a tilt-shift blur (a miniature-photo effect).

Six planning tools: radio masts, measure, route by slope (go, slow-go, no-go), ground profile, line of sight and area editing. Line of sight agrees with a full check on 98.4% of cells.

The camera no longer drifts after a zoom. The picture comes to rest and stays in focus.

Automatic quality settings, tuned on a laptop with integrated graphics: 42.4 fps while moving, and full quality 1.26 s after the camera stops.

A day display of the same scene. The switch between day and night takes 45 ms.

Two polish rounds after an independent review: labels kept off lines, level lakes, smooth map edges, and a slow pulse of light through the height lines.

Doors that block sight until breached, a flashbang, and a camera slid under the door.

Over 200 trials per setup, the share of the team alive rose from 48.6% with no tactics to 98.0% when the team plans its entry around the camera picture.

Standing orders: one member holds the hallway, and some defenders leave their posts to respond.

A stuck team no longer freezes for ever. On one hallway layout, wins rose from 175 to 190 of 200 trials.

Spoken squad orders. A fixed phrase table turns speech into orders, with no AI model in that path.

A radio analyst calls out only key events: 28 of 2,368 events in one four-room trial.

The spoken after-action briefing can be read in English or Simplified Chinese.

A real-time 3D view of the same simulation: about 7 ms of GPU time per frame at 1920×1080 on integrated graphics.

The design documents were rewritten. The game is desktop first; mobile waits for player feedback.

Your interview answers decide where your ship is posted, and the campaign remembers it.

A new game core: one ship in three sizes, the loan, the score and one game clock.

Renderer test on the target desktop GPU with about 9,500 sprites: 95% of WebGL2 redraws took 0.8 ms or less, against 13–24 ms for a 2D canvas and a 10 ms budget. WebGL2 became the default.

Sign-up: pick a size, sign the loan, and answer twelve questions while the hull is laid, then launch.

The builder: place modules on the deck plan and watch the yard build them. If the loan goes bad, the lender takes the ship.

Loan payments now start at launch, not while the ship is still in the yard.

The ship is drawn in 3D, with an exploded view, x-ray, labels and a parts list.

Orders by place: Shift-click the ground for a menu of what each team can do there. Greyed rows say why not.

Formation flight: two helicopters sent to one objective form up and fly in as one.

A two-storey house. The team moves up and down the stairs.

A new random town on every load. A seed in the address brings the same town back.

Air spacing: 20 m sideways or 10 m in height. From 27 September, a pass under 17 m counts as a failure.

Aircraft can crash. The wreck stays on the field, and missions continue around it.

1,004 of 1,004 missions completed over 250 random towns and one fixed map, with 0 crashes. Two passes came closer than 20 m but stayed above the 17 m limit. 330 of 330 automated tests pass.

On the new target laptop GPU, the unchanged S3 map runs at 265.7 fps at night: about 3.8 times the 70 fps floor.

The game skeleton: five aircraft, four hotspots, and gunship guns with real shell flight time and limited ammunition.

The world was rebuilt to match the original map pixel for pixel, in 10 of 10 test views.

Ground targets: a six-vehicle convoy and town traffic. Hold the sensor on a vehicle for 1.5 s to lock it.

A carrier with a fleet of 30 aircraft. Relief aircraft launch on their own.

An air traffic control panel: a board of every aircraft, a live top-down view of the ship, and a preview of each order.

Before the polish rounds, the slowest scene ran at 104 fps against the 70 fps floor, at 1920×1200.

Two visual polish rounds after an independent review: ship wake, deck crew, muzzle flash and label layout.

The first world runs by itself: a coast, a road, convoys and an AI attack jet that hunts them.

In four unattended runs of one game hour each, all 40 safety and behaviour checks passed.

Even the slowest 5% of frames run at 769 to 1,000 fps with the basic graphics, at 1920×1200 on a laptop GPU.

AI helicopters plan their own routes through a city and land on roof and street pads.

An automatic tuner trained the helicopter autopilot. On maps it never saw, a flight leg now takes 64.8 s instead of 101.1 s, with 0 crashes and 0 near-misses. Smooth arcs at the corners brought it to 63.8 s.

Six robotic helicopter docks on the carrier deck. As the ship pitches, each dock stays within 0.371 m of level (the limit is 0.4 m).

The rescue loop: after a convoy is hit, helicopters fly a team to the wreck and bring survivors and supplies back to the carrier. 56 rescues completed end to end in 20 test runs.

Sun shadows (in testing), clearer people, a visible dock arm and tapering smoke, after playtest feedback and an independent review. With shadows on, the slowest 5% of frames still run at 526 to 769 fps.

One playable mission in three phases: drop three soldiers in, knock out two missile sites and a radar, then call in a drone, a gunship and helicopters to capture three targets.

A four-minute clock, a team-health meter and a saved best time.

Automated tests play the game logic through a win, a loss and a restart. It is not yet tested on real phones.

First version, on stand-in data, with a check that no money appears or disappears.

Finer charts, drawn with braille dot characters (8 dots in each character).

Connected to the real economy simulation, read-only: all 193 of its files are unchanged after any run.

A lost connection no longer sets off a storm of retries.
