GRIMLINE is a top-down single-player zombie survival extraction game. You play as railway electrical technician Mara Voss, who restores an abandoned emergency train and turns it into a moving refuge through the infected ruins.

Enter the stations. Make it back alive.

Every stop is a dangerous expedition. Search buildings and industrial sites, manage limited ammunition, medicine and carrying space, and decide when the extra supplies are worth the risk. The farther you push, the harder it may be to return.

Build a home that keeps moving

What you recover changes life aboard the train. Store supplies, restore essential equipment, expand the cars and help rescued survivors recover and take on meaningful work. Fuel, medical capacity and maintenance determine which routes remain open.

Follow the line into the unknown

Mara is searching for her missing brother, but every signal reveals other people and communities struggling along the railway. Choose what the train can carry, who it can help, and what risks its growing community should share.

GRIMLINE is planned for Early Access. Development will expand the route network, station variety, train systems, survivors, progression and story with community feedback.
