In a fictional world very similar to ours of the 1980's, humanity suffers endless hordes of Kaiju and Abominations assaulting from all fronts. You play as a newly promoted Captain in the international military leading the defense as part of the aptly named Defense of Nations Treaty (DONT).
Your job should be straightforward: shoot monster, reload, shoot again, repeat until they're all dead or you are.
But after a couple decades of fighting against existential threats, it seems humanity has gotten comfortable enough—or at least familiar enough—with their situation to turn it into another giant, bureaucratic machine. Darn.
Ah well, better learn how to fake a smile and deflect their nonsense so you can get back to shooting eldritch horrors in the face for The Good of Humanity️.
