Yrminsul hits Steam tomorrow!
Release date: 02 March 2016

Have you had enough of nice and friendly heroes? Then become the villain of the piece! Get your own back on the pathetic forces of the good and make them finally understand that evil is something to be taken seriously, and must be well done. Resist their combined attacks during a game combining strategy and Tower Defense phases in a persistent universe. Make their islands, which make up this boring haven of peace, fall one by one. Evil spirits, boastfulness and a tendancy towards machievelic laughter will finally be rewarded through a title which renews the codes of the genre.



YRMINSUL is a strategy game in a persistent universe where each combat is held in the form of a Tower Defence. Crush the forces of good!

Tower Defense:
You love the frenzy of the tower defenses? Yrminsul is a fast paced tower defense in full 3D with a lot of content: +30 enemies, three types of enemy armies (Goblins, Monsters and Elves), 15 upgradable turrets, 16 spells and +30 levels with unique moods and design...

Before each attack, you have to choose carefully 4 turrets and 4 spells to use while defending. Knowing the enemies' strenght is important as you can go for single target damage or area of effect havoc; magic or physic damage; slow, stuns and other forms or control... Each army attacking you has its own strenghts and weaknesses, you have to know them to succeed!

Choose carefully which Island to invade, spy on the enemy to evaluate his forces. In Yrminsul, your opponents try to reclaim the islands you control. You will have to defend your territory from your enemies' sneaky attacks. At the same time, you will invade their Islands. You can go back and forth between the islands because the universe is persistent: when you build a turret, it will stay on its island unless the enemies gain control of the island.

Resource management:
In Yrminsul, you have to manage one main resource: Infamy. The infamy is your potential evilness and allows you to build defenses, to research new towers and spells, to spy on your enemies.... You have to manage carefully your infamy because you need to unlock new powers to face the strongest enemies. But doing so, would you have sufficient resources to defend your territory?

Universe and backstory:
As a RTS campaign, Yrminsul has a storyline and a universe you can explore. Each of the +30 levels has its own details and secrets, and more than 10 interactive comics unveil the story of Yrminsul!

  • +30 unique levels
  • +30 different enemies
  • 15 towers
  • 16 spells
  • A huge campaign
  • 100 ulockable interactive comic pages

Hey folks! The Game isn't dead and will be released in a couple months. We've tried to find a way to fund upgrades for Yrminsul but we couldn't manage to get what we where looking for. That being said we're happy with the current version of game and will post news about the overhaul we've working on. See you soon mateys!
