The year is 2301, and you are operating an agency to travel in time to correct issues created by beings called the Altuli.
On the Edge of Time is a cooperative 1-3 player game (with a 1 v all option).
The players attempt to complete missions to protect their timeline. These missions must be completed before the temporal stress reaches a critical mass, the universe splits and is destroyed.
During the game, two missions will be revealed, the Altuli will land on the game board and restrict your resources, temporal stress will be evaluated, and then players will take their turn.
In the player phase, individuals can spend credits to acquire units, use their temporal energy to travel and eliminate Altuli and utilize research to develop technologies.
Actions taken back in time will affect future points in time, sometimes with unintended consequences. Complete 6 missions and one final mission to succeed. Failure occurs if the temporal stress becomes excessive.
