## What is Grey Day?

A honeymoon in Seoul. A zombie outbreak. A journey that never ends.

GREY DAY: JOURNEY is an idle voxel survival adventure. Kate and Ryan walk across a fallen Seoul one landmark at a time — walking and fighting happen on their own. You choose their gear, their upgrades and when to make camp.

[17 SEOUL LANDMARKS]
Gwanghwamun, Gyeongbokgung, Myeongdong, Namsan Tower, the Han River, Gangnam, Lotte World Tower, Bukhansan and more — each built by hand in 5cm voxels. Past Bukhansan the road loops back, tougher every lap.

[FULLY AUTOMATIC]
No controls to learn. The couple walk, fight and talk on their own at a relaxed pace. Leave it running and watch the city go by.

[LOOT, SETS AND UPGRADES]
Zombies drop weapons, shields and armor in five grades with randomly rolled stats and affixes. Collect matching set pieces for set bonuses, and repair and upgrade your gear at camp.

[CAMPING AND FATIGUE]
Walking and fighting wear the couple out. Make camp, light a fire, heal and recover with camping gear — and chat by the fire. Roast marshmallows over the flames: pull them out at just the right moment for a golden treat.

[BOSSES]
A boss waits at the end of every landmark. Retreat, prepare and come back stronger. Hunt cleared bosses again for rare gear.

[SURVIVORS AND MERCHANTS]
Rescue survivors trapped in cars and behind barricades, and trade with wandering merchants.

[14 COSTUMES]
Tracksuits, long puffers, party wear, a tuxedo and hanbok. Fancier outfits come with bonus stats.

[WALK WITH OTHER TRAVELERS]
Faint echoes of players ahead of you appear on the road — pass them and climb the distance ranking. The top 3 walkers of each month receive gold in their mailbox.

[YOUR JOURNEY, SAVED]
Link your Apple or Google account to keep your progress and gold on our server, even when you change devices.

[A STORY ON THE ROAD]
Hundreds of conversations about the landmarks, the honeymoon they planned and the disaster around them — in 13 languages.

Free to play. Optional in-app purchases and rewarded ads. All crate odds are shown in the game. The journey plays offline; rankings, mail and server saves need an internet connection.
