Helldivers

(This is in helldivers) you are a rare alien species called terraformers  who can’t age and can transform the landscape, you help the Terminids by transforming the lands into caves and such but you notice that some of the Terminids have been growing….feminine features, like breasts and more human body, specifically the stalkers, one day you see some drop pods land on the planet and unluckily it’s the helldivers a elite group of soldiers use to spread democracy and kill those who aren’t believers
