Epic Flight Simulator : Slop Edition, Toronto Fly-Over Demo
The title is a joke. The flight sim is not.
Take off from Billy Bishop, skim Lake Ontario at golden hour, thread the Financial District towers and buzz the CN Tower SkyPod, over a Toronto built entirely from open data.
Toronto, rebuilt at every launch
There are no hand-made levels and no marketplace assets. Every building, road, tree, wave and lit window is generated from open data while the loading screen is up.
- 24 × 12 km of downtown, the waterfront and the Islands, with Billy Bishop (YTZ) and both runways, the Gardiner and the DVP bridges, parks and ravines.
- About 150,000 buildings at their surveyed heights, and about 95,000 trees placed from land-use data.
- Procedural facades with floors, window bays, shopfronts and curtain-wall towers that mirror the sky. At night thousands of windows light up and street lights trace the road network.
- A lake with animated waves and screen-space reflections of the skyline.
- A hand-coded CN Tower: tripod base, main pod, SkyPod, antenna, night lighting and beacons.
Built from OpenStreetMap, the City of Toronto 3D Massing model and open elevation data.

What's in the demo
-
6-DoF flight model
Stall and post-stall behaviour, propeller or jet thrust, flaps, landing gear, wind and turbulence.
-
Glass-cockpit HUD
Attitude, speed, altitude and heading tapes, VSI, G-meter, gear and brake indicators, a minimap and landmark labels. Push the SJ-9 too hard and you will meet OVERSPEED.
-
Flight assist
Attitude hold and auto-coordination for gamepads and casual flying. Press Tab to switch it off and fly the raw physics.
-
Morning, golden hour, night
Sky atmosphere, sun and moon, volumetric clouds and fog. Press T in flight to move the clock.
-
Four cameras, full gamepad
Chase, cockpit, orbit and flyby. Left stick to fly, right stick to look around, triggers for throttle.
-
Slop detected
Crash and the game tells you so, then respawns you after 4 seconds. R, Enter, Space, A or Y skips the wait.
Pick a prop or a jet

Sloperjet
For when you've got the hang of the prop. Fast and loud, so take it low over the lake or through the Financial District.

14 rings, one clock
The sightseeing gate tour is a timed route through glowing rings: from the Sunnyside waterfront past Ontario Place, the CN Tower, City Hall, Casa Loma and the Don Valley, to the finish at Centre Island. Crashing costs you time.
Landmark teleports Press 1–9 in flight, or try them here.

W pushes the nose down, like pushing the stick. Press I to invert pitch.

First take-off
In the SW-1, hold Shift for full power, then ease back with S at about 55 kt.
How the city gets built
Unreal Engine 5.7, C++ only. The game boots into an empty map and builds Toronto itself. We didn't place a single building by hand. The CN Tower, we did.

A headless editor pass generates six materials and imports the ground texture. Only what changed gets rebuilt.

Runtime
C++ builds Toronto
Terrain, buildings, trees, bridges, streets, lane paint, street lamps, cars and the lake are meshed on worker threads behind the loading screen.

Questions
When is it out?
There's no date yet. It's coming to the Epic Games Store and will be free to play. If you have questions in the meantime, get in touch.
Why "Slop Edition"?
It's a joke, and it stops at the name. Underneath is a 6-DoF flight model with stall and post-stall behaviour, wind and turbulence, over a city built from open data.
How accurate is the city?
About 150,000 buildings are extruded to their surveyed heights from the City of Toronto's 3D Massing model. Water, parks, roads, rail and runways come from OpenStreetMap, and the terrain from open elevation data. The facades and lighting are procedural, so it's stylised, but the streets are where they should be.
Can I find my house?
If it's inside the 24 × 12 km box around downtown, the waterfront and the Islands, there's a good chance it's there, at its surveyed height.
Can I play with a gamepad?
Yes. Leave Flight assist on for attitude hold and auto-coordination, or switch it off with right on the D-pad for raw physics.
I keep crashing.
Check the pitch first: W pushes the nose down, and I inverts it. Then take the SW-1 with Flight assist on, hold Shift for full power and ease back with S at about 55 kt. After a crash you respawn in 4 seconds, or straight away with R.
Why does the first launch take a while?
Shaders compile once on first launch. Give it a few minutes; after that it starts in seconds.
Go fly Toronto.
Mind the SkyPod.
