The Loop
Desert canyon: the line climbs from the bottom onto mesas on trestles. Two stations, enemies come in one group. A sandstorm blows in from time to time.

Missions
Ten missions across six lands: from the desert loop to the raiders’ lair with the final boss.
Map
Missions unlock in order. Complete a mission on any difficulty to unlock the next one, and come back for the stars later.

World
Desert canyons, autumn forest, tundra, summer forest, sea coast and scorched wasteland. Each land has its own stations, trees, rails and weather.
Terrain is part of the game: the line climbs onto plateaus on trestles, dips into cuttings and crosses canyons on high bridges. A heavy train goes slower uphill and speeds up downhill.
Mission 8 “The Dam”: the line along the crest above the canyonMissions
Desert canyon: the line climbs from the bottom onto mesas on trestles. Two stations, enemies come in one group. A sandstorm blows in from time to time.
Autumn forest: a lake at the bottom of a bowl, the loop runs along its slope and up onto the ridge. A branch goes down to East Station by the water, vans rob the vaults.
Snowy tundra: a loop around the rim of a basin, a link goes down to the bottom between frozen lakes. In a blizzard the guns reach less and the train barely crawls.
Summer forest: a river in a deep gorge cuts the loop in half, crossed by two high bridges on stone piers. Thunderstorms roll in, and lightning strikes the enemies.
Canyon at sunset: two rings on mesas and a run along a high trestle across the canyon. Four stations and only one train.
Sea coast: three islands with sheer cliffs and three high bridges. Crabs crawl out of the sea, and in the fifth wave the King Crab rises from the deep.
Snowy pass: a huge figure eight, and at the saddle the line passes over itself on a stone viaduct. Branches to the quarry and the mine.
Autumn forest: a reservoir on the plateau is held by a dam across the gorge, and the line runs right along its crest. A branch goes down to the power station on a ledge.
A seaside town rises from the harbor in ledges. The drawbridge over the canal is raised once a minute for a steamer, and crabs crawl out of the harbor.
The finale. Scorched wasteland: a loop around the rim of a huge crater with a dark lake and a mine at the bottom. The gang has its own line around the lair, and in the last wave its armored train comes out.

| Easy | New to the genre | Enemies are slower and weaker, more coins, rail repairs are cheaper |
| Normal | Intended balance | As designed: every wave needs a plan |
| Hard | For experienced engineers | More enemies, attacks come at once, the boss fires more often |
