Smile Protocol
SteamSmile Protocol is a high-pressure FPS survival experience set inside a sealed facility.
To progress, you must open doors. To open doors, you must survive.
How you survive… is entirely up to you.
Every door is a test.
To access new areas, you must clear incoming enemy waves. Each wave becomes faster, denser, and more lethal.
Play aggressively or take it slow — the pace is shaped by your decisions.
The experience isn’t limited to one path.
Choose how you want to play:
In Endless mode, enemies never stop. The tempo keeps rising.
At some point… it’s no longer about survival — it’s about how long you can last.
The facility is watching you.
If cameras detect you, enemies are redirected to your location. Alarms trigger instantly, increasing pressure.
Destroy cameras and stay in control — or embrace the chaos and fight through it.
Not every target is the same.
Some enemies wear helmets. The first shot breaks their defense. The second shot kills.
Target priority is the key to survival.
The environment is not just background — it’s a tool.
Place electric traps to slow enemies, control areas, and manage pressure.
A well-placed trap can save you… or recover from a mistake.
You choose the rules.
Play a more classic experience — or enable a harsher challenge:
Enemies take no damage from body shots. Only headshots can stop them.
This mode tests your aim and precision.
Some rooms contain people waiting to be rescued.
Stay near them to earn rewards. Leave, and the process is canceled.
Take the risk… or keep moving forward.
There is no single way to survive.
Every decision changes the flow of the game.
Weapon handling is fully in your hands:
Play fast and risky — or controlled and precise.
Customize your experience:
Create a balanced experience — or a brutal nightmare that punishes every mistake.
⚠️ If you choose the harder path, the game will warn you. But once you commit… there’s no turning back.
