Venice Unleashed enables user-generated content for Battlefield 3 (BF3). You and others in the community are able to write custom gamemodes, game logic (script extensions), and create entirely new content with Rime, their custom Frostbite editor.

You need to own a valid BF3 license. Venice Unleashed functions without any connection to Electronic Arts (EA). Goodbye, Origin and Battle Log. Hello, in-game server browser. You are no longer limited to hosting game matches with only a few server providers. All users are able to privately host dedicated servers.

EA/DICE's annoying artist expresssions like in-game blue tint and a blinding super nova sun can be adjusted to desirable levels. You are no longer restricted to one soldier. The out of bounds barrier can be removed and the control points moved.

With the new spectator mode for BF3, you can freely roam a map or follow a player in 1st or 3rd person. This allows for better film editing creations and makes detecting cheaters much easier.

Give Venice Unleashed a try!
