Welcome to the Sanatorium, hidden high in the mountains, where we train the best of the best - our future cosmonauts.

We are pleased to welcome you into our ranks, recruit. Despite the nasty rumors about you, claiming that you are not who you say you are.

MAY NO ONE BE LEFT BEHIND is a thought-provoking, sarcastic, and at times utterly bizarre adventure that will immerse you in a world of alternate history and may even take you to space... probably.

Century-old history

A universe where an unstoppable force known as the Collective has brought the world into perfect order under The Global Government. For a hundred years, humanity has enjoyed peace and prosperity, but discontent is growing in the shadows. Those who call themselves the Patriots long for the old ways. They want to speak their native languages again and restore the traditions. They are willing to do whatever it takes.

A memorable cast

The crew for the next mission is ready. The Sanatorium staff are performing the final medical examinations. Nothing can stop the march of history. Oh... wait. It seems you've all been locked up and are being tortured! What better time to get to know those around you? Some will offer a kind word, others will share fascinating stories, and some may even become your closest friends. Just remember one thing - you can't be friends with everyone. Or can you...?

What else?

• Observer Effect - a mysterious cosmic mold has found its way into the Sanatorium. It plays by its own rules but only when nobody is watching. How do you deal with something you can't see? Here's a hint: cameras.

• Maintain secrecy - the world is divided between two political factions: the Collective and the Patriots. Pick a side and act accordingly. Or ignore them both and say whatever you want - but be prepared to face the consequences.

• Solve puzzles - secret passages, an intriguing story, conversations, and a touch of psychological horror. Uncover the Collective's greatest conspiracy and decide the fate of The Global Government.
