Polygod

Polygod is a randomly generated rogue-like first-person shooter with a brutal difficulty curve. Combining the fast-paced style of Quake with the randomness, difficulty and power-up system of The Binding of Isaac, Polygod is a hardcore gamer's and speedrunner's dream. Only the most experienced and strategic players will be able to win the Trial of the Gods. You are the Faceless One: the legendary one-armed gun-wielding assassin. 7 deities will test your skills in randomly generated arenas with hostile minions, followed by a boss battle against a ruthless holy champion. Each of the arenas has 5 altars of worship, offering you blessings in exchange for the souls you have collected on your journey. Blessings combine and stack to create unique weapon effects, but each has its own consequences. so choose wisely if you want to survive every evil challenge.
