# Arma 3
### From their [Site](https://arma3.com/)
Experience true combat gameplay in a massive military sandbox. Deploying a wide variety of single- and multiplayer content, over 20 vehicles and 40 weapons, and limitless opportunities for content creation, this is the PC’s premier military game. Authentic, diverse, open - Arma 3 sends you to war.

### Installation Requirements
- A valid, real Steam account, with Steam Guard turned off, is required to install the server (default "anonymous" login cannot be used). For security reasons it is recommended that you create a new Steam account just for your dedicated servers. This account *does not* need to own Arma 3.
- For automatic Steam Workshop mod downloading to work, the Steam account *does* need to own Arma 3. This is, of course, optional functionality, and mods can be manually uploaded to the server if desired.

### Minimum RAM Warning
This server requires about 2048 MB to run properly.

### CPU Usage Information
ARMA 3 is mainly CPU intensive. Contrary to popular belief, the server binary *can* run on multiple cores/threads. However, it's ability to manage asynchronous tasks and hyperthread is *very* limited, meaning additional cores/threads reach diminishing returns very quickly. In addition, it's ability to utilize all of the CPU alloted to it for AI processing seems to be limited as well. Therefore, a [headless client](https://community.bistudio.com/wiki/Arma_3_Headless_Client) ***and*** a properly written mission file are highly recommended if large amounts of AI units will be used. An Arma 3 Headless Client Egg can be found [here](arma3_headless_client).

### Additional Settings
Additional server flags can be found [here](https://community.bistudio.com/wiki/Arma_3_Startup_Parameters).  
These can help you fine tune how the server will behave during runtime.

*Note: The `-maxMem=` flag is currently known to cause an unknown segmentaion fault crash on startup. Other hardware related flags may cause similar behavior.*

### Server Ports
Default server ports. It is [recommended](https://community.bistudio.com/wiki/Arma_3:_Dedicated_Server#Port_Forwarding) that each server be 100 ports seperate from each other.

| Port | Default |

| Arma 3 Game & VON | 2302 |
| Steam Query (+1) | 2303 |
| Steam Port (+2) | 2304 |

#### Mods/Plugins may require ports to be added to the server.
