To do this, simply find a robot teleporter in the past and destroy it to get a good future. Alternatively you can get all the Time Stones in the game to get an automatic good future for every zone. Regardless, once you have acquired a good future, from the past, run past a “Future” sign to be warped to the present and from the present find another “Future” sign post to run past to get to the Good Future. Beat the level from here. The achievement will pop up during your score tally. NOTE: This achievement is missable if you never destroy any robot teleporters or don’t get all time stones if avoiding robot teleporters.
