Legion shows up in the lobby and confuses every new player at least once. Here's what it actually is.
Legion isn't a mod. It's an official third faction currently in development. That means it's playable in most lobbies, but it's not finished content. Some features will appear, shift, or disappear as the faction gets built out. Treat it as an option worth trying, not the final product.
Playing navy as Legion means you're effectively playing Cortex ships. The faction borrows the Cortex navy roster until dedicated Legion naval units arrive. If you go into a naval match expecting unique Legion ships, you'll be disappointed. If you play it as Cortex with a different coat of paint, you'll hold your own. The real fun comes once Legion gets its own dedicated ships, whenever those ship in a future update.
Some players hit a screen that says "connecting" and never moves past it. This is usually a firewall or network setting, not a game bug. Check that your firewall isn't blocking the BAR executable, verify your internet connection is stable, and restart the client if it hangs. Account creation problems also tie back to this — the game needs a clean connection to register a new player.
When you join a random lobby and the other player picks Legion, you want to know what you're facing before units hit the field. Understanding Legion's current roster cuts out the ten minutes of confused poking that costs games in early-match skirmishes.
Crd is the first really comfortable community I have been a part of. Everyone is nice and kind, the atmosphere is relaxed, and I am not getting yelled at for not being optimal.
