About this game
Story Summary of Last Signal
Last Signal is a horror game set in a remote watchtower overlooking a restricted park. You play as Mark, a man sitting at home checking his email, waiting for a response for a job. With no reply and bills piling up, he accepts a job working a night shift as a security guard.
His task seems simple: monitor the park, keep trespassers out, and most importantly, keep the generator running.
The job pays $500 a night.
The generator powers the lights that keep the area visible, and if it shuts down, unknown creatures start coming at you.
Patrol systems, check cameras, and respond to minor issues.
But soon, the power begins to fail more frequently.
The cameras glitch, showing things that weren’t there before.
A strange signal starts coming through the radio, filled with distorted voices and warnings.
Some messages sound like lost people begging for help, while others feel like something trying to lure you outside.
As the nights continue, the situation becomes more dangerous.
The longer the lights stay off, the closer the unknown presence gets.
You must leave the safety of the tower to restart the generator, risking an encounter in the darkness.
Meanwhile, Mark’s text messages begin to fill with messages that don’t make sense. Messages that seem to know where he is.
In Last Signal, survival depends on one thing: keep the generator running, when the lights go out, something is already on its way.
THIS GAME ONLY INCLUDE NIGHT 1. DLC's ARE SEPARATE.
