About Annulus

Annulus is a dark‑fantasy tactical strategy game that puts you in command of a mercenary legion across the war‑torn continent of Novisess. Powered by Unreal Engine, it blends medieval‑style warfare with Lovecraftian visuals, offering a sweeping storyline and cinematic CGs.

You recruit, train, and evolve mercenaries of three races—Orcs, Elves, and Humans—while managing weapons, resources, and a unique Contamination Value system that adds buffs and debuffs. Weather, terrain, and day‑night cycles all affect combat, making each battle a fresh tactical puzzle.

01 / THE GUIDE

Mercenary Recruitment and Evolution

Players collect mercenaries, each with distinct traits, and can train them to level up. As mercenaries advance, their forms, attributes, and skills evolve, sometimes gaining entirely new designs tied to their narrative backgrounds.

Evolved mercenaries unlock more elaborate skill effects and exclusive “character auras,” which influence formation strategy and overall team strength.

  • Observe how a mercenary’s aura interacts with nearby units to fine‑tune your formation.
  • Compare early‑level and evolved skill visuals to gauge the impact of upgrades.

Environmental Effects on Battle

Random weather and elemental interactions trigger varied combat effects. Terrain, day–night cycles, and vegetation directly influence mercenary performance, adding a layer of strategic depth.

These environmental factors combine with the Contamination Value system, which provides additional buffs or debuffs that can shift the tide of battle.

  • Test the same unit in different weather conditions to see performance changes.
  • Use night conditions to explore how day–night cycles affect mercenary performance.

Contamination Value System

The Contamination Value system adds impactful buffs and debuffs during combat, enhancing immersion and unpredictability. It works alongside environmental influences to test tactical decision‑making.

Managing this system effectively can turn a disadvantageous position into a winning one, especially when combined with skill synergies.

  • Track how contamination buffs affect your tank units versus damage dealers.
  • Pair contamination debuffs with mercenaries that have decay or knockback abilities.

04 / THE GUIDE

Story Choices and Battle Events

Beyond the main storyline, side tales react to player choices, sometimes spawning new battle events. These events deepen the medieval fantasy immersion and can alter narrative direction.

Each decision can shift the story’s path, encouraging multiple playthroughs to experience all possible outcomes.

  • Save before major choices to compare different narrative branches.
  • Note which battle events appear after specific side‑quest completions.

05 / THE GUIDE

World Exploration and Resource Gathering

The world map features exploration points such as eerie forests and treacherous mountain passes. Dispatching squads to these locations uncovers rare resources needed for mercenary development.

Environmental detail, from lighting to realistic weather, creates an immersive backdrop for these exploration missions.

  • Try dispatching squads to different exploration points to compare the resources each offers.
  • Observe how weather changes affect mercenary performance in different regions.
