Arma Reforger’s biggest update yet adds the volcanic Kolguyev map, the Operation Omega singleplayer campaign, and a complete Conflict HQC rework where a Commander role manages AI logistics and builds bases anywhere on the island. New weapons: RPG-22, RPG-75, hand flares. Server hardware tip: Kolguyev’s dense AI logistics + HQC base construction is notably more CPU-intensive than vanilla Everon Conflict — plan your plan tier accordingly.
Arma Reforger is Bohemia Interactive’s bridge to Arma 4 — built from scratch on the Enfusion engine with native crossplay between PC and Xbox, proper dedicated server support from day one, and a mod ecosystem that’s already producing serious total-conversion content. But the Enfusion engine’s AI-heavy game modes (Game Master with 200+ AI units, HQC logistics networks) demand more from server hardware than most mil-sim titles. Getting the wrong provider means laggy vehicles, AI that rubber-bands across Everon and sessions that crash during Conflict’s peak. Choosing from the best game server hosting UK providers matters more here than it does for lighter games. This guide focuses specifically on UK players — London node latency, GBP pricing and hardware specs that actually handle Reforger’s demands.
Unlike pure PvP games, Reforger’s most popular modes (Game Master, Combat Ops, HQC) run significant AI unit counts simultaneously. A Game Master scenario with 150 AI soldiers, vehicles and helicopters is CPU-intensive in a way that a 64-player pure-PvP server isn’t. The Enfusion engine is multi-threaded but AI pathfinding and state machines are demanding.
Without the -maxFPS 60 launch flag, the Arma Reforger dedicated server will consume all available CPU resources even when idle — driving clock speed unnecessarily high and burning through server time. Always confirm your managed host applies this flag by default. Most reputable hosts do, but it’s worth verifying.
Arma Reforger supports PC and Xbox crossplay. PS5 mod support is pending Sony approval as of April 2026. If your unit has Xbox players, confirm your host’s server appears correctly in the Xbox server browser — some providers need specific configuration. Set crossPlatform: true and supportedPlatforms correctly in server.json.
Arma Reforger’s coordinated team operations — radio comms, vehicle syncing, squad spawning — are highly sensitive to latency. A London UK server gives British players under 20ms. Frankfurt adds 35–60ms on top of simulation load. At those numbers, vehicle handoffs, heli landings and respawn timing feel noticeably different.

Arma Reforger maps — Everon, Arland & Kolguyev
Arma Reforger currently has three maps, each with different scale, AI demand and server requirements. The map you choose affects hosting costs — a Kolguyev HQC session with 64 players and full AI logistics demands significantly more CPU than a small Everon Game Master op with 16 players.
The classic from Operation Flashpoint, recreated 1:1 in the Enfusion engine. Green rolling hills, forests, towns and coastlines. Home to the vanilla Conflict mode and most community mods. Best starting map — most players and missions are designed around Everon. Medium CPU demand for standard scenarios.
A smaller, more compact island map with varied coastal terrain. Good for faster-paced Conflict and Combat Ops. Less built-up than Everon, with more open sight lines across its terrain. Moderate CPU demand — similar to Everon but slightly lighter due to fewer urban areas.
Added in Update 1.6 (October 2025). A rugged volcanic island with pine forests, rocky ridges, hot springs and abandoned coal industry sites. Home to the new Conflict HQC mode and the Operation Omega singleplayer campaign. Most CPU-intensive map — HQC’s AI logistics, base construction anywhere, and commander role add significant simulation demand vs classic Conflict.
Conflict HQC, Game Master & Combat Ops — which mode for your server?
Arma Reforger’s game modes have very different server resource profiles. Choosing the right mode for your hardware tier prevents performance issues before they happen.
The flagship large-scale PvP mode, overhauled in Update 1.6 into Headquarters Commander mode. A Commander player manages AI logistics units, directs supply chains, and can build bases anywhere on the island. Other players earn ranks by completing objectives and teamwork. High CPU load — AI logistics units + dynamic base construction + large player counts creates the highest simulation demand of any Reforger mode.
A designated Game Master controls the scenario in real time — spawning AI units, vehicles, objectives and events from a top-down view. Popular for mil-sim units running structured operations. CPU load scales with what the GM deploys — a GM with 200 AI infantry, armour and air assets is very demanding; a GM running a small 20-player patrol mission is moderate. Plan hardware for your unit’s typical GM op scale.
Cooperative AI-versus-players missions with predefined objectives. Players work together to complete scenarios against AI opposition. Also available on Kolguyev as of Update 1.6. Most predictable resource load — AI count is bounded by the scenario, making hardware planning straightforward. Good starting mode for new server owners who want PvE without a Game Master.
Arma Reforger server specs — RAM & CPU by scenario type
Unlike Space Engineers (single-threaded), Reforger’s Enfusion engine is multi-threaded — cores matter alongside clock speed. However, AI pathfinding and state machine updates still benefit disproportionately from high single-core performance. The optimal server spec depends heavily on what game mode and AI count you’re running, not just player count.
| Scenario | Players | Min RAM | Recommended RAM | CPU |
|---|---|---|---|---|
| Small vanilla Combat Ops | 4–16 | 4GB | 8GB | 4 cores @ 3.5GHz+ |
| Everon Conflict (classic) | 16–64 | 8GB | 12–16GB | 6 cores @ 4.0GHz+ |
| Game Master — moderate AI (100 units) | 8–32 | 8GB | 12–16GB | 6–8 cores @ 4.4GHz+ |
| Kolguyev Conflict HQC (64 players) | 32–64 | 12GB | 16–24GB | 8 cores @ 4.4GHz+ |
| Kolguyev HQC + heavy Game Master (128p) | 64–128 | 32GB | 48–64GB | 12+ cores @ 4.4GHz+ |
| Heavy modded server (total conversion) | 32–64 | 16GB | 24–32GB | High clock · 8+ cores |
Without this launch flag, the server binary runs uncapped and consumes all available CPU even when idle. Most managed hosts apply it by default — verify before your first session. Running without it on shared hosting can trigger throttling from other customers’ servers.
Reforger servers download and verify mods at startup. A heavy modpack on SATA SSD can take several minutes to load; on NVMe it’s seconds. Important for managed servers with daily restarts or frequent update cycles.
Enfusion is multi-threaded — AI processing, physics and network operations can distribute across cores. Both clock speed and core count matter. A Ryzen 9 9950X (16-core, 5GHz+) is close to ideal. Don’t pick a 4-core entry server for 64-player HQC.
Reforger dedicated servers are headless — no rendering, no GPU needed. All hosting plans for managed game servers are CPU + RAM only. If a provider mentions GPU for game hosting, that’s marketing, not a technical requirement for server operation.
Required server ports
gameHostBindPort: 2001 and gameHostRegisterPort: 2001 in server.json. Managed hosts configure these automatically.server.json — Arma Reforger’s configuration file explained
Unlike most older Arma titles, Reforger uses a clean JSON config file — server.json (or config.json depending on setup). Here’s a complete working example with the settings that matter most for a UK community server.
Controls the maximum draw distance on the server. Lower values (2000–2500) reduce CPU and network load. The default 3000m is appropriate for open operations but increases what the server must track and sync. On Kolguyev HQC with 64+ players, reducing to 2000 can noticeably improve performance.
Defines the radius within which the server syncs entity states to each client. Lower values (800–1000m) reduce bandwidth and CPU load on busy servers. Set too low and players will see vehicles appearing suddenly — find a balance for your typical engagement range.
To allow Xbox players, set crossPlatform: true and add "PLATFORM_XBL" to supportedPlatforms. Your server then appears in both the PC and Xbox server browsers. PS5 support works similarly when Bohemia finalises it — watch for Sony approval updates.
The GUID of the scenario to run. Official scenario IDs for Conflict (Everon and Kolguyev), Game Master, and Combat Ops are in Bohemia’s documentation. Workshop scenario IDs come from the mod’s Workshop page. Change this to switch maps and modes.
Mods & Workshop on Arma Reforger servers
Arma Reforger has a Steam Workshop with an integrated mod browser — players download mods automatically when connecting to a modded server. Server-side mod configuration goes in the "mods" array of server.json. Each mod entry needs its modId (from the Workshop URL) and optionally a version.
The most popular Reforger mod — adds dozens of factions, weapons, vehicles and equipment from various Cold War era nations. Massively expands Game Master and Workshop scenarios. Widely used by mil-sim units. High content volume — verify mod compatibility before stacking with other faction mods.
Adds the ability to dig trenches and foxholes in Reforger’s terrain. Essential for defensive scenario design and mil-sim realism. Server-side with automatic client download. Lightweight with minimal performance impact relative to the gameplay value added.
A persistent sandbox scenario where players fight an ongoing guerrilla conflict on Everon. Popular persistent-world community server mode. Resource requirements scale with how many players are active and how many towns have been liberated. A good alternative to pure Conflict for PvE-focused communities.
As of April 2026, PS5 mod support is pending Sony approval. PS5 players can currently join PC and Xbox crossplay servers but cannot use mods. If your server runs mods, PS5 players will not be able to connect until Bohemia finalises the Sony agreement. Monitor the official Reforger roadmap for updates.
PC, Xbox & PS5 crossplay on Arma Reforger servers

Arma Reforger server hosting — frequently asked questions
crossPlatform: true and add "PLATFORM_XBL" to your supportedPlatforms array in server.json. Your server then appears in both the PC Steam browser and the Xbox in-game server browser. PS5 players can join PC and Xbox servers in vanilla mode, but PS5 mod support is pending Sony’s approval as of April 2026. Once that approval is confirmed, PS5 players will be able to use mods on crossplay servers. If your server runs mods, PS5 players currently cannot connect.-maxFPS 60 launch flag caps the simulation at 60 ticks per second, which is the maximum supported by the game logic and more than sufficient for stable gameplay. Without it on shared hosting, your server consumes server resources unnecessarily, triggering throttling from the host. Most reputable managed hosts (LOW.MS, Host Havoc, GTX Gaming) apply this flag automatically — but verify it in the launch parameters section of your control panel."mods" array of your server.json file. Each mod needs its modId (found in the Steam Workshop page URL) and an optional name. When the server starts, it downloads any missing mods automatically. When a player connects, their Reforger client automatically downloads the server’s mod list before spawning — there’s no manual mod installation step for players. This is significantly smoother than Arma 3’s mod management. PC and Xbox players can use mods; PS5 mod support is pending Sony approval as of April 2026.gameHostBindPort: 2001 and gameHostRegisterPort: 2001 in server.json. Additionally, if you want to use BattlEye RCon for admin tools, UDP 17777 is the default RCon port (configurable in BEServer_x64.cfg — add RConPort 17777 at the end of the file). Managed hosts configure the main port automatically; you only need to manually set the RCon port if you’re using external admin tools like TADST or BE-RCON.
