YASS

YASS is a top-down shooter-looter: pick one of two characters, fight through two floors of sealed rooms, and collect guns rolled with their own grade, stats and modifiers, plus rare uniques with a mechanic of their own.

Ammo is shared by each weapon family and runs short, so you keep switching guns, while every few rooms a roulette card makes the enemies tougher.

Made in 30 days as a prototyping challenge.
