Warframe is best understood as MMO-lite rather than a simple six-person campaign game: many normal missions are smaller squads, while clans, hubs, open zones, events, and social progression give larger groups reasons to play around the same ecosystem. The moment-to-moment play is fast third-person action with parkour, abilities, loot farming, crafting, and account-wide progression. It fits groups that like long-term progression and can tolerate different activity caps across modes.
