Hello, I am Ondrej Petrzilka, for those who don't know me I am the lead developer for Space and Medieval Engineers. I joined Keen Software House in 2011 as a game programmer for Miner Wars 2081 and since then I have worked on various projects in the studio mostly on the development of Space Engineers. In this blog post I would like to put some light on our current and future plans with Space Engineers. Currently we’re working on three big things: planets, scenarios and new multiplayer.

Medieval Engineers is back in action with a great new update! With the introduction of a highly detailed planet, a phenomenal world map that shows a symbolic depiction of the world, a fully updated rendering engine and many optimizations. Engineering in medieval times has never been this awesome. Not to mention all the other new additions to the game, like doors, new particles, a wardrobe, land ownership, and finally the ability to play as a female engineer!

This blog post begins with the same words I used in my Space Engineers for Xbox One post: let me assure you that the retail release of Space Engineers in US/EU/AU stores has no effect on our development plan, priorities or the game you are playing and following right now.

Biography

I have always been driven by the need to create — games, AI agents, ideas. That’s why I started Keen Software House: to create games that only existed in my head. After Space Engineers took off, I founded GoodAI to develop AGI, to help humanity and understand the universe.

These days I’m focused on Space Engineers 2, the VRAGE3 engine, AI People, and autonomous agents in general — powering NPCs in our games, or swarms of autonomous and intelligent drones.

It’s all part of my long-term plan: to make civilization stronger, greater, and more resilient.

Our home base is a 17th-century Oranžérie in Prague — but we’re a remote-first, global team of 100+ programmers, artists, designers, and engineers.

I am proudly European , and in the last few years, I’ve come to love South Africa and its people.
