What makes the game stand out

The store listing describes generated maps, weapon upgrades, a mystery box and a hidden ritual. Changing layouts can make each run less about memorizing a route and more about adapting to the space in front of the team.

Who may want to try it

Players who enjoy surviving waves with friends may appreciate the familiar round-based structure, while the procedural approach aims to keep navigation unsettled. The demo is a chance to see how the maps and progression distinguish it from its inspirations.

Playable demo: Yes — Play the Mortuus demo on Steam.

Hello, Rowan here, I generally play a lot of single player RPGs specifically games with fast paced action and a distinct story line like Exp33 or Elden Ring. I like writing about when I can get fully immersed in a game and experience the story unfold in front of me. Or that my choices carry weight on what happens. Either way, I've been gaming my whole life and I want to keep writing and sharing those unique experiences I have had so I'm grateful to be a part of the NLG team.
