The FOnline Engine is an MMORPG engine, developed by Russian Fallout fans. The engine is in no way connected to Interplay's Project V13 (Fallout Online), the official Fallout MMO. The FOnline Engine was created from scratch and supports original Fallout, Fallout 2, Fallout: Tactics, Arcanum and Baldur's Gate graphic and sound assets.

The development of FOnline (Engine) started in early 2004.

SDK Release

On September 1, 2010, the FOnline SDK was released. It is now possible to create your own multiplayer and singleplayer games based on the FOnline Engine. The general developer chat can be found at #fodev on


Fights are either in real-time (like FT) or turn-based (like F1/F2), and the choice of which combat style to play is left to you, so depending on your preferences you can either take part in tactical, action-management battles or a series of frantic react-or-die brawls.

If a player dies, he will respawn in special locations, called "Replication Stations", with all memories up to the moment of death. Money (in the form of bottle caps) is taken from the player for the cloning process. The player will spawn with the default blue overalls and the pip-boy, at which point they will wish you 'Good day'. All items, implants and money will remain on the corpse, which can be looted. Dead players' corpses persist in the game world for a few minutes, then they, and all equipment on the corpse, will disappear.


All quests will be divided into groups: Cycle-based (Clean up a shelter, clear a area of wreckage, repair the generator), Disposable (Become a paladin of Brotherhood of Steel or become a citizen of Vault-City) and Unique (Save the world). While cycle-based quests will be available to players from time to time, Disposable quests will be available to one-time only to a limited number of players. Unique quests may be completed only once per game session. Considering the variety of the Fallout world, we hope that they will keep everyone entertained.

Open Test

The third open beta test started on August 15, 2009, and will hold until the official release of the engine. Also notable is, that on August 25, 2009, the first open test of FOnline: 2238 started. A game based on the FOnline engine which started out as simple modification, called "Faction Mod" and turned into it's own game after the game became much more than just a "Faction mod".

Games based on the FOnline Engine

FOnline: The Life After

The first game based on the FOnline engine was FOnline: The Life After. It was only developed in russian and english. The game is set in the year 2246 on the Fallout 2 worldmap.

FOnline: 2238

FOnline: 2238 was a Fallout game based on the FOnline engine, but the project has since been closed.  The game was set in the year 2238, 3 years before Fallout 2 starts and uses the Fallout 1 and 2 worldmap combined into one, allowing players to explore and adventure through the entire 'classic' Fallout world. It also includes an expansive system of professions and crafting items to promote a Player-based economy. The main feature of this game is the ability to enlist with existing canon organisations (such as the mighty Brotherhood of Steel, the up-and-coming NCR or the sinister Enclave), join a player-created faction or even form your own wasteland gang.

Fonline: Reloaded

FOnline: Reloaded is a reboot of FOnline 2238, striving to fix many of the issues that made FOnline 2238 frustrating for some. It promises improved PVP functionality, uncapped leveling, rare item accessibility, better quests and dungeons, and easier crafting. Its first test run should happen starting 8/31/2013.

FOnline: Ashes of Phoenix

FOnline: Ashes of Phoenixis a game based on FOnline engine, but unlike the other FOnline is set in a completely new area, that being the city of Phoenix, and has a completely new map. It is primarly focused on the various factions fighting over control of the city.

FOnline 2:

This is the latest and most anticipated of all FOnline projects. Featuring hundreds of new features, a totally reworked crafting system, new vehicles and items, PvP and PvE quests, and the largest and friendliest english speaking community, it is sure to remain the premiere FOnline game. See, their forums.


It is possible to build new games with the FOnline engine, which are 100% independent from all Fallout content. Thanks to this, it is also possible to use the engine for commercial projects.
