The flight
The run launches from a river oasis at one end of the course, where a blue waterway winds between rocky hills, green fields, reed patches, and clusters of small buildings and trees. From there the route crosses two large stone pyramids set side by side mid-course, each flanked by smaller gateway structures. Past the pyramids the course opens onto bare dunes dotted with palm trees, scattered ruins, and a lone brick building that marks the far end of the roughly 4,530-unit flight.
Upgrades in this world
Each stage is 5 levels. Engine and Slingshot share the same price curve, so their early levels cost the same. The full level-by-level table, with the plane’s evolution at each unlock, is on the Solar plane page.

| Income | 5 | 25 | 100 | 5.05M |
| Slingshot | 4 | 20 | 3.91M | 134.58B |

Engine is the money pit: 92% of the 1.78T it takes to max this world. Income pays for itself fastest, so keep it ahead of the other two.
