Steam Train Fest ends
Hostile military territory. A beautiful spy, dressed in a mini dress, approaches a key official of the enemy government.
She successfully gathers intelligence using a honey trap, but is captured and forced into a desperate escape.
The only way forward is to cross a dangerous minefield filled with countless buried explosives.
Using the numbers hidden beneath the tiles as clues, she must deduce where the mines are buried.
But this is no ordinary minesweeper.
Armed drones patrol overhead, missing not even the slightest movement.
If she takes too long, the drones will launch a relentless attack.
Every step demands careful judgment. A single mistake means instant death.
Will she find a safe path and escape—
or step on a mine that ends everything?
