The First Descendant

The First Descendant is free, has full crossplay across PC, PlayStation, and Xbox, and its squad PvE loop is functional and sometimes genuinely fun. The reason it does not crack the main list is that the monetisation is aggressive in ways that become hard to ignore after a few hours, and it does not do anything that Warframe does not do better in the same space. For groups who have exhausted the options above or specifically want something with zero upfront cost, it is worth a look. Just go in with expectations calibrated.

The First Descendant gets you into four-player co-op boss fights fast — faster than almost anything else here. The Intercept encounters, where squads coordinate ability usage against large targets with defined attack windows, are genuinely fun and designed around team roles. That's the good news. The honest news is that character unlock timers for several Descendants stretch past 72 hours, which is a deliberate push toward buying Caliber to skip the wait. The core loop is free and functional, but the monetization pressure on the roster is more aggressive than most games on this list. Worth playing if you want quick squad action and can tune out the unlock friction — just go in knowing it's there.
