writes: id Software is well known for publicly releasing the source code of its old first-person-shooter games. Now Croteam is joining the club by releasing the source code of the engine of the very first Serious Sam game. It's the very same engine that the company used for Serious Sam Classic: The First Encounter and The Second Encounter. Croteam's Vyacheslav Nikitenko, who worked on the source code and prepared Serious Engine v.1.10 for this release, had this to say: "Historically, this version of Serious Engine is very important for Croteam and for me personally. I created several mods for Serious Sam back in the day, before even starting the work on the source code, and it was a great tool for learning. And it's even better today! Obviously, Serious Engine v1.10 won't produce top-notch graphics, but the source code is very well commented, easy to modify, and there are lots of user generated mods out there. This version has everything you need to build your own game – or just experiment. If you're looking to get started, just download the files from GitHub and head over to SeriousZone, it has a great community and lots of tutorials." Happy hacking!
(And here's a video with some game play
that shows what this engine can do.)
