Time heals all wounds, they say, but the sudden death of a loved one sometimes shakes those who are left behind so much that their faith wavers. To prevent this, the gods send fate weavers to change the past and prevent death. In the game series UNDO, players slip into the role of these destiny weavers and do everything in their power to undo sudden deaths — whether murder or suicide. Not only do they travel minutes or hours back in time, but sometimes thousands of years to change events that have laid the foundation for the later stroke of fate.

The UNDO series combines the theme of time travel with emotional, extraordinary stories that players must assemble piece by piece. Each time jump gives them another choice in how they can change the past — and not every change is a turn for the better!
