About this game

The Deceptive Silence: Someone is at the door. Your phone says it’s a loved one, but your instincts scream otherwise. Who do you trust?
Psychological Standoff: Use limited clues, sound, and visual glitches to distinguish between survivors and "them."

One Mistake is Fatal: A single choice to open the door can end it all. Can you survive until dawn?
But beware! Unknown zombies lurk within the fog, and once infected, you too will become one of them. Yet, mutation seems to bring more than just danger...

Destruction
• Resources are the foundation of everything—try to gather them from your surroundings.
• Smash through obstacles in your way and collect scattered materials.
• Destroy everything in sight at will.

Development
• Build temporary shelters and upgrade your weapons.
• Repair UV facilities to shield yourself from mutation.
• Try to rebuild your vehicle and unlock new adventure zones.

Adventure
• The fog conceals the unknown, and sudden enemy attacks pose the greatest threat.
• Stay calm—your firepower is limited.
• Fix your car and explore vastly different environments.

Mutation
• Attempt to control your mutation—danger and opportunity go hand in hand.
• Choose from multiple mutation paths, unlocking new abilities and appearances.
• Be careful! Without UV protection, always monitor your limits.

There are a lot of improvements that I would like to see. I do enjoy the game but would enjoy it so much more if we were able to speed things up with diamonds ( or the equivalent of), upgrade our weapon ourselves, and many more things that I've also thought about. Again, I do like the games but please consider thinking about making it more in-depth or alow us to customize our character the way we see fit. Possible male and female to choose from allowing us to make the characters look different

This game was great. 100% free. Huge. No ads. No store. And then you ruined it. My loading screen was frozen and after I cleared my data now I know why. You completely changed the game entirely. It's barely the same game anymore. Now you can't go back to previous locations. You don't keep any of the resources you got. Then, when you're done with all three locations, you do some stupid town building thing and ridiculously simple and stupid battles. You completely destroyed the game.

Awesome game!! It's fun. The graphics are awesome. I did find one teeny typo that doesn't affect the ability to play the game. When you are building the bridge in the second map location;it shows a picture of cement but the text above the picture says "gas". EDIT: publish an update please and thank you!!
