SHORT ANSWER

TrainWars is a free graffiti game you can play online with friends. Make a room, send the link, and up to 8 writers paint the same train or wall at the same time, in a computer browser with nothing to install. Every stroke, drip and fill shows up on everyone's screen as it is sprayed.

Graffiti has always been social. You go to the yard with your crew, someone keeps an eye on the gate, you split the letters, you share caps, and afterwards you stand back together and take the photo. Most graffiti games leave all of that out: it is you, alone, with a wall. TrainWars has online rooms to put the crew back in.

How a room works

  1. Sign in. Rooms are for TrainWars accounts. Signing up is free and takes an email address.
  2. Make a room. Press Play, pick Online, then Make a room and choose a map. You get a 6-letter room code and a link.
  3. Send the link. Your friends open it, or type the code under Join a room. Up to 8 players fit in one room.
  4. Paint. In a private room the host starts the session from the waiting room. A public room has no waiting room: players walk straight in.

Open public rooms also show on the TrainWars start page, with the map and how many players are in. A full room is marked Full.

Which maps you can paint together

Every player in a room needs the room's map. The free maps only need a free account.

Painting with other people: what works

Painting with others is a different skill from painting alone. A few things that make a room session better:

Keeping what you painted

A room is not saved: when everyone has gone, its wall goes too. To keep a piece, take a photo with the camera button, or save the whole wall to your blackbook as a page while you are still in the room. Photos can go on the community wall, where other players like them. The MIGHTY piece above was posted there.

The rules in public rooms

The first time each day you walk into a public room, two rules come up:

  1. Don't cross work in progress. Leave other players' pieces alone while they paint.
  2. No hate. No hateful messages in the chat, and none in your paint.

Open the player list from the player count and press Report next to a name. The report takes a screenshot of what you see and the player's last chat lines. When enough players in the room report the same writer, that writer is taken out of the room and cannot come back to it. Every report also goes to the TrainWars team, who can ban an account from online rooms.

Other multiplayer graffiti games

Most graffiti games are single player. Bomb Rush Cyberfunk and Jet Set Radio are played alone, and so is Marc Ecko's Getting Up. In VR, Kingspray Graffiti has had online multiplayer for years, and Graffism VR lists multiplayer among its plans. If you do not own a headset, TrainWars runs in the browser you already have.

Frequently asked questions

Is there a multiplayer graffiti game?

Yes. TrainWars has online rooms where up to 8 players paint the same subway train or station wall together in real time, in the browser. In VR, Kingspray Graffiti also has multiplayer.

Can I paint graffiti online with friends for free?

Yes. Making and joining rooms is free with a TrainWars account (sign-in by email). The free maps work in rooms; the Full Game maps need every player in the room to own the Full Game.

How many players fit in one room?

Up to 8 at the same time.

Does my friend need the same map?

Yes. Every player needs the room's map. On a free map that is only a free account.

Is the painting in a room saved?

The wall lives in the room while people are in it. Take a photo, or save the wall to your blackbook as a page, before the last player leaves: an empty public room starts clean.

Can I play rooms on my phone?

Rooms work in a desktop or laptop browser for now. A room link opened on a phone tells you to open it on a computer.

What happens if someone ruins a piece?

Every player in a public room can report another player, with a screenshot. Players reported by others are taken out of the room, and an account can be banned from online rooms.
