A game called Eternal Threads is free to own forever.
As long as you claim a copy before 16:00 UTC on the 26th October.
The complete narrative follows the six main characters through multiple decisions across multiple timelines and you can experience these in any way you choose.
You can concentrate on just one particular character’s storyline at a time, following their choices across the timelines and then go back to the start and follow another character.
You can approach the story like a forensic detective, observe the final outcomes of the story and then work backwards along the timeline – essentially observing the effects and then determining their cause.
Or you can just watch things in chronological order, experiencing the timeline unfold as you observe and change the decisions that the characters face as the week progresses.
