Last Rails Sandbox

The year is 2199. The world is almost gone.
A dangerous virus has turned millions of people into zombies. Cities are destroyed, and people are hiding to survive. But far to the south, in the old lands of Mexico, there are rumors of a cure that can stop the virus.
You board an armored train — the only way through the zombie-filled wasteland. You'll have to fight zombies, find supplies, and make tough choices to reach your goal.
Can you save yourself and others — or will the zombies get there first?
