The max online player limit is define in local configuration file. Thus, we can simply edit the file and remove the limit. Only the host need to edit the config file. Follow these steps to see how to edit:

多人連線的人數限制其實是在本機的設定檔中定義，因此我們可以透過修改檔案的方式移除人數限制，這些設定只要開房的主機端修改即可，以下將按步驟教學如何修改:

• Open your Steam Library and find Risk of Rain. Right click on it and choose Properties.
  開啟你的Steam遊戲庫並找到Risk of Rain，在上面按右鍵並選擇遊戲內容
  
  
• Select Local Files tab and click on Browse Local Files...
  選擇本地檔案頁面，並點選瀏覽本地檔案
  
• Open prefs.ini with your text editor.
  找到prefs.ini這個檔案，並用文字編輯軟體開啟
  
• Scroll down and find max_players_online.
  往下捲動並找到max_players_online這個參數
  
  
• Edit the number as you want and save the file. It's all done!
  把數值改為想要的然後存檔，即大功告成！

Here are some screenshots for coop over 4 players! :D
以下是一些超過四人的多人連線遊戲截圖！ :D

Risk of Rain is design for 4 players coop as optimal. Although you can edit the file to remove the restriction and play 4+ coop, there might be some balance problem such as items are not enough for all player. However, how many players do you want to play with is all your choice!
Any problems or suggestions are welcome to comment below :D

原本Risk of Rain的設計是四人連線是最佳的，雖然可以透過修改檔案解除人數限制，但或許會碰到一些平衡問題，例如物品不夠大家拿，不過最後究竟要和多少人連線，這些決定都在於玩家！
