New navigation, Russian translation in progress

Everything is now reachable from the sidebar on the left: news, guides, calculators, and simulations. The filter box at the top of the sidebar searches every entry, so a growing list of guides stays one keystroke away instead of a long scroll.

The language menu sits in the top bar. Your choice is remembered in this browser. Russian is available as a fourth language, with untranslated content falling back to English while the translation continues. The item and building names were translated by hand and may differ from the wording in your game client — corrections are welcome on Discord.
