The Map Editor is a mode where the player can create a map for online play or simply to try out his own sandbox 'world'. The map editor of Far Cry 2 is a tool used to create customised multiplayer maps. The terrain available ranges from desert, to savannah, to woodland, to jungle. The player can add objects such as buildings, weapons, ammunition boxes and various types of vegetation. Hand held weapons are not available to put into maps, as multiplayer uses a class system akin to the more recent games in the Call of Duty series, although the player can add mounted guns such as the M249 and the M2 .50 cal. The maps, once created, can be uploaded to the respective map server of the console. The map can then be 'launched' to test it out directly in the game with nothing but an AK-47 and an Eagle .50 (that never runs out of ammo or jams). The player is also invincible in this test mode (this can be changed in the Pause menu). Return to the map editor at will to add more content or change things that did not work as expected. The map editor can be used to create wide areas of terrain, from wide deserts to close-quarters urban environments. Some players also use the map editor to create 'training' maps, e.g.: a firing range or assault course. Players can also create escape-type maps featuring puzzles that are made by the player, but the aforementioned puzzles are not part of the map editor and have to be crafted through exploitation of the physics engine. The editing process begins with nothing but solid ground. Then use the toolbox option to place down objects such as Assault Trucks or buildings in the map. Additionally the terrain can be altered and the environmental settings changed. There are many more options letting you edit your map in Far Cry 2: The Map Editor in Far Cry 3 is not very different from Far Cry 2's Map Editor. One of the new and notable features is that you can place handheld weapons, AI, and Vehicles, but these are only for personal use. Like in Far Cry 2, it is mainly used for Multiplayer, and sometimes just to mess around. As said in the above segment: AI, Handheld weapons, and Vehicles are only for personal use. This means that only one player can play it in the map editor. To make a playable Multiplayer map, your map must be valid for the wanted gamemodes. To get your map validated, you will need to go to Gamemodes, then go to Global. Here, select End Movie, and place it where you want. This will be where the ending scene of the match takes place. You then must make spawn points for the Blue Team and Red Team, as well as make the shared spawn points (BT: 9 RT: 9 Shared: 10) You must also have none of the Items stated only for Personal Use, and you will also need to place everything needed in your gamemode in good places. Each gamemode will need different spawn points. Once you are done, you will need to save your map, name it, publish it, and start up a beta test. Here, you can test your map with others, or just watch others play it. The Map Editor once again appears in Far Cry 4, which acts similar to Far Cry 2 and Far Cry 3. Yet there is no multiplayer support yet, other than the recently added Co-Op feature. Far Cry 4's map editor is now used for singleplayer missions and co-op missions. People normally make full missions to express their creativity, some just make random maps that are meant to be fun. The reason has not been stated, it may be them trying a different approach. The answer has not been made clear, nor has any mention of a multiplayer update been hinted at in anyway. There are modifies which can change the game, set loadouts and change the overall difficulty of the map. Modifiers are mostly used for invincible maps or sole stealth maps. Hiding the HUD, however, does not work since the players can turn it back on via the game settings. There are 34 loadouts to choose from, all of which are detailed here. There are 30 presets and 4 custom loadouts for the player to create. They are listed below. Source.
