Adds the missing ways to learn Astronomy, Surgery and Biology, from the computer or from a book. With 100+ ratings, it was one of the most-subscribed mods of the game's early release.

Everaldo Sembiring outdoors among autumn larches, mountains behindTen years of making games: lead programmer, console porter, then five years of AAA plugins at AccelByte.

I started in the game industry with five years of making games as a lead programmer and console porter. Then I spent five years as a software engineering manager at AccelByte, building plugins that empower the development of AAA titles like The Callisto Protocol, Splitgate and SUPERVIVE.

Now I lead from the product side, with deep programming knowledge and a player’s instinct for what makes a game work. I also make game mods, some for hire and some for fun. And I still play games every day, while I co-found an independent studio. More soon.

What I do

Six things I am good at. Pick one to see it.

  • Gameplay, battle systems and the code that holds a game together, from LEGRAND LEGACY to three jam games.

  • Porting games to consoles and optimising them to run well, on current hardware like PlayStation 5 and Nintendo Switch 2.

  • Ludum Dare 32 and 33: a whole game, from idea to download, in one weekend.

  • At AccelByte, whose backend powers games like The Callisto Protocol, Splitgate and SUPERVIVE. I started the pipeline that checks every plugin on Windows, Linux and consoles.

  • Hands-on in all three, Unreal in C++. Learned the long way, without leaning on AI assistants.

  • Deciding what a game should be and getting a team there, with the code knowledge to know what it costs.
