: You can easily invite friends via your Steam friends list or join public lobbies through the built-in matchmaking system.

: Unlike classic artillery games (like Worms), Interplanetary uses a simultaneous turn system. Everyone plans their shots, builds structures, and manages resources at once.

: The Enhanced Edition improved the networking architecture, making it easier to reconnect to ongoing games if a connection is lost.

: You can play live sessions where everyone takes their turns simultaneously, or utilize the "hotseat" and asynchronous online modes for longer-running games.

: If you don't have enough human players, you can fill empty slots with AI to maintain the scale of the war.
