Indium Games

' was a stormy, dark and drunken night, when a group of vagabonds gathered around the glow of a computer monitor to form an alliance. They planned to create
the best game in the world.
To their misfortune, they failed.

Fortunately, they were too stubborn to surrender their efforts.

Today, our goal is to learn and innovate; always sharing what we've learned with you.

This desire to learn led to the creation of HactEngine, an open source game engine. HactEngine is cross-platform, simple but extensible, and always getting better. Join the community and be a part of its future!

We’re committed to making high-quality games with an emphasis on story, originality and fun.

Players should be a part of the development process, so we’re sharing our progress with you. We’re always looking for feedback (good and bad), so be in touch:

Short presentation video about HactEngine and Hero Killer, which we used at ICT Showroom 2014.

  • Hero Killer image

    Hero Killer

    Project Hero Killer will be our first short game project. In this game you have to prevent invincible heroes from stealing your precious heirlooms, hopefully killing them in the process.

    Careful planning of your security system will ensure that you can stop the treasure-robbing heroes and keep what is “rightfully” yours. But your security system has to stand the test of time.

    Time modification will play a huge part in this playful puzzle game. You will play the part of the evil genius, who designs the levels. The hero will try to survive your deadly traps and you must improve your blueprints until they fail.

    In our game - Unhuman - you’ve been infected with a deadly disease and you are trying to survive in a quarantined city, where you are about to face the horrors of true “human nature”. You need to fight the disease for the control of your mind.

    Explore the city and find a way to survive. Gathering supplies and interacting with other survivors will help you on your way to get out of the city, but beware: not all of who you meet are friendly. Your choices will affect the city and its residents; and there will be more than one way out.


HactEngine is an open source and cross-platform game engine. It uses open standards and open file formats. Almost everything in the engine can be modified while your game is running.

The engine’s core is written in C++ and uses the popular Qt application framework as its base. It uses OpenGL for graphics and let’s you write your own shaders or you can use the ones that come with the engine.

The engine uses Lua for scripting. Lua is extremely easy to learn, but also incredibly powerful. Because of Lua, the engine supports live editing: almost everything in your game can be modified while the game is running.

HactEngine also provides easy-to-use editors for modifying the game world. You can modify the editors or write your own to fit your game.

HactEngine is being built by Indium Games and will be released as open source during 2015.

Equipped with his trustworthy quill, he is now eager to embark for this new and glorious quest with his brave companions.

In his early life Antti used to be a humble pirate chef who sailed on the “salty” coasts of Finland.

One day he decided to sink his ship and find some new adventures in the mystical world of programming. He found himself in a seedy tavern where he met his new companions.

Now he is wielding a mighty spade that he uses for digging up treasures that are buried between lines of code.
