One Last Time

The long awaited space-ship of their rescue had just descended. The last stranded remains of mankind, the Declan Twins are about to exit the earth-or atleast, were.
A mysterious verbal transmission, inturrupting them-erupted a last minute plan-change. A whole new revelation-there were survivors left behind, when there shouldn't be anymore...
A 'short' detour and a rescue before they can embark on their journey.
Just "One last time" alright?
It'll be quick.

'famous last words.'
In a world abandoned due to the sun's radiation turning Fatal, stranded twins are forced to confront lurking dangers. That's when they realise-

The sun wasn't even the worst part yet...

Once they see you, it's over.
With the clock ticking, and their lives now endangered, they are now bound together by the need to survive. The characters race against an ever-decreasing window of opportunity. Every decision is a gamble, and every step taken brings them closer to either salvation-or death.
