Diluvian Ultra

Diluvian Ultra is a single-player, first-person shooter focusing on a retro aesthetic and fast-paced, strategic combat. The game is set in its own expansive fictive universe. Rather than gritty or dark, Diluvian Ultra is colorful and fantastical, like the cover of pulp sci-fi novels of the past.

“Actually a very fun game. It's too bad that my save has none of the weapons that I collected, and is effectively bricked. Looking at the other reviews this seems to be a common issue. Super unfortunate.”
