Thief simulator

Thief Simulator is a commercial stealth game on PC and consoles. LifeSim is a free browser game with no stealing mini-games or crime how-tos. Instead, you play the social drama of a former thief who wants out, or a legal security tester. It runs on a real 3D map of Earth.

A safecracker who wants to go straight

How to play a thief in LifeSim

Describe your character in the text box, such as a former thief going straight or a legal security tester.
Name a real city like London, Paris, or Las Vegas in the text to start on that real 3D map.
Edit your cast to add an old crew member, a locksmith mentor, or a corporate client.
Use place search to walk to real museums, banks, or jewelry districts and talk to people in your own words.

How to play this role in LifeSim

LifeSim has no stealing system, no crime mechanics, and no career ladder. You start by writing your character in one text box. Many players write a veteran safecracker who wants out of the underworld, or a legal physical penetration tester.

You build the story through your life goals, your daily to-do list, and the people around you. You can edit your cast to add an old crew member or a strict corporate boss. People keep a journal of past events and remember what you tell them.

A day in the life in London

You start your morning in London. In the real world, this work splits between daytime observation shifts and late-night off-hours shifts. You check your daily to-do list and use place search to walk to the Hatton Garden jewelry district.

The map shows real streets and buildings from the outside only, with no interiors. For a legal tester, the routine means casing entry points and writing vulnerability reports. At night, an old contact texts you, and the day ends with a recap of your moments.

A sample life: going straight in Boston

Ray, 42, is a former burglar in Boston who wants a clean life as a physical security consultant. He sets a life goal to pass his background check and stay away from his old fence. On Tuesday, he plans an outing with a new friend near the Isabella Stewart Gardner Museum in Fenway-Kenmore.

Mid-week, his old partner texts him to ask for one last favor at a warehouse. Ray refuses in his own words, and the partner remembers that answer the next time they meet. On Friday, Ray goes to a birthday drinks happening on the map to meet new people.

The hard parts of the life as story

Real people in this field describe long, boring hours spent waiting on cold street corners. Those in the illicit trade face paranoia, isolation, and the inability to trust coworkers. Even legal Red Teamers face high stress when guards detain them to check their paperwork.

In LifeSim, you play this tension through conversations and group text threads. If you lie to your partner about where you were at night, they remember it later. Your chats and activities can change your money, your health, and your relationships.

Real cities for a security or heist story

In London, the Hatton Garden district is famous for the 2015 underground vault burglary at Hatton Garden Safe Deposit Ltd. In Paris, history centers on the Louvre Museum, the Musée d'Art Moderne, and the jewelers of Place Vendôme.

In Boston, the Isabella Stewart Gardner Museum is the site of the famous unsolved 1990 art theft. In Las Vegas, the casinos on the Strip employ top vault security teams. The city also hosts the annual DEF CON security conference and its Lockpick Village.
