You can use the in-game chat system to get help, using the /help and /report buttons.
For general or gameplay-related questions, use /help. This will send your question to any Supporters who are online. The /help command works like this:
citoj:/help how do I [your question here]?
citoj:/help how do I move troops across water?
To report a player for cheating, hacking, or violating atWar rules, use /report to contact the Moderators. The /report command works like this:
citoj:/report [player name] is [breaking x rule] in [link to the game]
citoj:/report Dave is hacking in https://atwar-game.com/games/?link=7917584467
You can use /report even when no moderators are online -- your report will be saved and reviewed by the next available Moderator.
