IRSEN
A downloadable game for Windows
About This Game
IRSEN is a turn-based roguelite where your character fights alone against coordinated enemy squads.
Explore procedurally generated dungeons, collect genes from defeated enemies, unlock new skills, and reshape your build during each run.
You Are the Boss
In IRSEN, you don’t play as a fragile hero. You are the encounter.
Enemy groups act with coordination and tactical intent. Every battle is deliberate. Every mistake is punished. Target selection, action order, cooldown timing, and effective use of skills determine your survival.
Procedural Descent
Explore procedurally generated dungeons and descend floor by floor. Each level increases enemy strength and tactical pressure.
But your greatest enemy is mutation. The deeper you go, the more unstable your evolution becomes.
Push forward — or collapse under corruption.
Gene System and Progression
Develop your character through the gene system: combine genes, form gene chains, unlock new skills, and modify their properties.
Corruption builds up over the course of a run. The deeper you descend, the stronger its influence becomes: your character gains mutations, and full overload means death.
Enemies and Combat
In each squad, enemies perform different roles and act together:
- protecting allies;
- drawing attacks away from key targets;
- healing the wounded;
- applying negative effects;
- finishing off weakened targets.
The combat system rewards thoughtful decisions: target selection, action order, cooldown timing, and effective use of skills determine your survival.
Genetic Lab
Inside the Genetic Lab, you can reshape your build during a run:
- improve gene alleles;
- stabilize or destabilize genes;
- recombine skill properties;
- synthesize new genes;
- recycle unused properties and research adaptations.
No two combinations are identical.
Modes and Gameplay
Each run is built around adapting your character:
- experiment with builds;
- discover synergies;
- adjust to new threats.
In the standard mode, you can reshape your build during a run using the Gene Lab, adapting skill properties to fit your strategy.
In Iron Will mode, skill properties remain random: you must build around what you manage to find and adapt to the flow of the run.
Core Features
- Turn-based battles against coordinated enemy squads.
- Enemy squads with coordinated AI roles.
- Build development through genes, properties, and skill chains.
- The ability to reshape your skills during a run.
- Procedurally generated dungeon progression.
- Growing corruption, mutations, and the risk of death from overload.
- Two ways to play: controlled build shaping or adapting to randomness.
IRSEN is a solo-developed project focused on tactical buildcraft, enemy synergy, and gene-driven progression.
