Isochrons are created by analysing several samples believed to have formed at the same time from a common source.
The Re-Os isochron plots the ratio of radiogenic Rhenium and Osmium were strongly refractory and siderophile during the initial accretion of the Earth which caused both elements to preferentially enter the Earth's core.
In Allison Road you will take on the role of the unnamed protagonist, who wakes up one day without any recollection of prior events.
Over the course of five nights it is your objective to uncover the whereabouts of your family, unravel the mysteries of the house, and face off against Lily and other dark entities that are nested deep within its walls, while the clock is relentlessly ticking towards am.
Bill Skarsgard, who plays the evil clown, spoke out on the sequel before it was officially confirmed.
