About Smile Protocol

Smile Protocol is OxygenStudio’s single-player survival shooter in Steam Early Access. Each run through a hostile facility pays out coins and case keys as you fight encounters, buy equipment and push the next door.

Story Mode unlocks new sectors. Wave Mode asks you to clear a set number of harder waves. Endless Hostage Mode has you hold a position while foes grow stronger, with the option to extract and keep what you earned. A Trader turns coins into more case keys. A shop sells weapons, ammunition, armour, health supplies, grenades and equipment before you go back in. Unlocked weapon skins, attachments, gloves, grenade skins and cosmetics stay in your collection. You pick Humanoids, Aliens or Skeletons before a run, and custom rules change reload behaviour, enemy count, speed and type — including a headshot-only option that raises the reward multiplier. OxygenStudio plans a 6–12 month Early Access window while combat pacing, enemy behaviour and progression are tuned with player feedback.

Key Features

Rewarded survival runs: Fight encounters, earn coins and case keys, then return with a stronger loadout.
Case collection: Open cases for weapon skins, attachments, gloves, grenade skins and other cosmetics that stay unlocked.
Story Mode: Unlock new facility sectors and manage resources as threats wait behind each door.
Wave Mode: Clear a fixed number of escalating waves for keys and resources.
Endless Hostage Mode: Defend a position with no final wave, then extract when you want to secure earnings.
Trader and shop: Convert coins into case keys, or buy weapons, ammo, armour, health, grenades and gear.
Enemy types: Choose Humanoids, Aliens or Skeletons before you enter.
Custom rules: Adjust reload, enemy count, speed and type; harder settings raise the reward multiplier.
