I'll keep it short for the third game:
Both humans and Locust are fucked up after the events of the second game, trying to rebuild among the ruins. In the meantime, the lambent situation has gotten worse. They're appearing on the surface, mutating and worse of all jumped species, resulting in zombie humans. But thankfully, Marcus' dad is developing a ""cure"". Myrrah has him hostage so he can also cure all the locust as well, but there's no time. Marcus fights his way to him on a secret government island obscured by an artificial storm, kills the queen and the sci-fi beacon is activated. All lambent are killed, this includes the locust since they are a by product of lambent infusion for their initial creation. All is saved and humanity can have a huge fuckfest to revive the population.
Ignore the sequels
