The launch trailer is pretty good, though I honestly feel like the actual graphics at launch turned out better than the trailer showed.
In short, on one side of the war it's Starship Troopers. On the other side, it's the Terminator Wars. There is a developer assigned to act as a DM of sorts, and they influence the way the war unfolds while the entire community fights to achieve the goals of said war.
The game is both very fun and very challenging. It has a good balance of making you feel completely badass one moment, and then absolutely humbling you moments later. The missions can get very intense at a moment's notice. I've also had a pretty good time playing with randoms, and toxicity is incredibly rare (I have yet to encounter any, myself).
I fix giant metal birds that light themselves on fire and scream really loud to fly across the sky. The kingdom heavily regulates who fixes them, how they fix them, and who flies them to make sure everyone is safe.
