This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.

1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.

2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.

3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.

4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

Hearts Under Guard is an adult romance visual novel. Play as Hayes, a close-protection lead at an East Hampton oceanfront estate. A kidnap threat tightens security and three women pull you past every professional line you've sworn to hold. Three routes, each with explicit adult scenes.

In a house built for privacy, the most dangerous line is the one you stand on every day.

You are Hayes—a veteran close-protection operator newly promoted to lead the security detail at a twelve-acre East Hampton oceanfront compound. Your job: perimeter checks, protocol, and never crossing the one rule that keeps the operation clean. But when a credible kidnap threat locks down the estate and a hostile corporate bid squeezes the household from the outside, three women pull you into private moments that stop feeling procedural fast.

Meet the Cast

Piper — The Cover
Celine's personal assistant—hyper-competent, impeccably placed, and just a little too clean to be accidental. Hayes clocks her tradecraft early, and what begins as surveillance turns into a dangerous intimacy built on mutual recognition: two professionals who know exactly what they are.



Celine — The Second Position
Richard Crane's second wife: polished, strategic, and bored in the specific way only a perfectly managed life can produce. She doesn't ask for romance like a fantasy—she negotiates it like infrastructure, with clear eyes and a schedule.



Tatum — The Principal
The 21-year-old heiress who's spent her whole life under protection—smart enough to see the cage, quiet enough to survive it, and engaged to a future she didn't entirely choose. Hayes is the first operator she's looked at directly, not as furniture, but as a person.

Key Features

• Single-choice branching romance: One pivotal decision launches you into a focused, character-driven route with a distinct tone, power dynamic, and ending.
  
• Proximity as the core tension: Executive protection turns closeness into currency—every conversation, corridor, and routine check becomes charged.
  
• The compound as a living stage: Front-of-house perfection versus backstage intimacy, with secrets unfolding in pool houses, service corridors, and the gate-keeper's cottage.
  
• Ambient stakes, constant pressure: A kidnap threat and a hostile bid create a slow-burn atmosphere where nobody panics—until it matters.
  
• Three romances, three kinds of risk: The principal, the spouse, and the plant—each relationship offers a different kind of heat, consequence, and emotional cost.

Adult Content

Each romance route includes explicit adult scenes. Contains nudity, sexual content, and mature themes including power imbalance and infidelity.
