One More Volley

The demons took Black Raven Valley. The gold is still there. So every night, one stubborn gunslinger walks through the portal — kills until the valley is knee-deep in coin, and then faces the only decision that matters: leave rich, or stay for one more volley.
Extract or die trying.
Survive escalating waves of demons across a hand-built valley — abandoned villages, flooded graveyards, a dead forest that watches back. Gold you carry is gold you can lose: walk out through the portal and bank all of it, or die and keep a salvaged cut. The portal is always the safe choice. The next wave is always the richer one.
The build is the game.
You move. Your arsenal fires on its own. Every level-up deals a hand of cards — new guns, upgrades, and trinkets of debatable value. Max a gun, max its paired artifact, and it evolves into something the demons file complaints about.
Features:
A hand-crafted valley, not a random soup — every road, graveyard, and ruin placed on purpose; only the run itself is unpredictable

Eight gun classes — from a crowd-shoving blunderbuss to a lightning turret with opinions

Weapon evolutions — pair the right gun with the right relic and reforge it mid-run

Artifacts of pathetic power — cursed trinkets, questionable sausages, a famous liar's glass eye; the world is grim, the treasures are embarrassing

The extraction decision — bank everything at the portal or gamble the haul on one more wave

Meta progression — spend banked gold in the village between raids; death pays, just poorly

Bosses with manners — every deadly thing telegraphs before it kills you

Short runs, long consequences — ~20 minutes a raid, benchmark auto-tuning, and a valley that remembers being paid
