"Set after the alien wars depicted in the retro Contras, Contra: Rogue Corps is concerned with a mysterious alien city that rises from the ruins, which is supposed to be full of treasure that we assuredly want, but doesn't seem to be doing anything besides sitting there and having treasure and monsters, which is a classic example of a "non-plot." A depressingly common setting for live-service multiplayer video games: A plot with no active villain, or ticking clock, or clear solution, just an environment with a sense of permanent, non-specific peril that can never change or develop for fear that XxNobChopsxX might stop his grindy, 8-hour quest to make themselves able to grind 1.8% more efficiently."
