This guide will walk you through the complete process of porting an existing ARMA Reforger map to work with Overthrow. The process involves creating a new addon, setting up the world, and configuring all the necessary Overthrow systems.
If you are the creator of a map, we recommend that you do not perform the following steps in your map addon. Instead create a new addon that depends on your map, and Overthrow.
First, you'll need to create a new addon that will contain your ported map:
Create New Addon
Overthrow - <Map Name> (e.g., "Overthrow - Everon Extended")Set Dependencies
Your addon needs these dependencies:
Note: Do not add any weapon/faction etc mods such as RHS. They are not required, players can choose whether or not to add these themselves. Only set the minimum required dependancies to get the core of Overthrow working.
Now you'll create your own version of the world that you can modify:
Open the Base Map
MapAddon/Worlds/MapName.ent)Create Your World
OverthrowMapName)WorldsOVT_Campaign_MapName✅ Checkpoint: You now have your own editable version of the world!
Time to add the essential Overthrow components:
Create Organization Layers
OVT_Campaign_MapName)townsbasesmanagersslotsmiscAdd Core Managers
managers layer and Set as activeOverthrow/Prefabs/GameModeOVT_OverthrowGameMode.etOVT_OverthrowFactionManager.etMost maps already include these, but check if any are missing:
Required Base Game Managers:
How to check:
Note: The location of these entities doesn't matter. From this point forward, placement will be important.
Towns are the heart of Overthrow's economy and progression system:
Prepare the Towns Layer
towns layer and Set ActiveOVT_TownController.etResearch Existing Towns
SCR_MapDescriptorComponentPlace Town Controllers
For each village, town, and city:
OVT_TownController.et to the center of the settlementOVT_TownControllerComponent and set:
#Map_Loc_TownName)Town_TownNameWithNoSpacesMilitary bases provide strategic objectives and resources:
Prepare the Bases Layer
bases layer and Set ActiveOVT_BaseController.etPlace Base Controllers
For each military installation:
OVT_BaseControllerComponent and set:
Base_BaseNameWithNoSpacesOVT_VehiclePatrolSpawnPoint prefab on a road in a safe position just outside any gates, make sure it's facing the direction of the roadIf your map uses standard ARMA Reforger buildings, you can skip to Step 8!
For maps with unique buildings, you'll need to configure:
Shops & Vehicle Dealers:
OVT_ShopComponent to buildingCashierShop_01.et prefab, orActionsManagerComponent with OVT_ShopActionStarting Houses:
Override prefabs and add:
OVT_ParkingComponent (car spawn location)OVT_SpawnPointComponent (player spawn)OVT_OverthrowConfigComponentBuyable Houses:
OVT_RealEstateConfig entriesActivate Misc Layer

OVT_StartCameraPos with good view for main menuOVT_FallbackHomePos near a bus stop in a townSignBusStop_01.et prefabs or entities with:
SCR_MapDescriptorComponent set to "Bus Stop"ActionsManagerComponent with OVT_CatchBusAction⚠️ Critical: Delete all save files in ArmaReforgerWorkbench/Profile/.db folder
Make your map available to players:
Create Mission Folder
