Open Source Java Real Time Strategy Games for Linux

Arianne is a multiplayer online engine to develop turn based and real time games, providing a simple way of creating the game server rules and clients like our MORPG Stendhal. Our engine Marauroa uses Java and SQL for hosting hundreds of players on a solo host. Stendhal is a fun friendly and free multiplayer online adventure game with a huge and rich world. With hundreds of NPCs and different quests, features like the Travel log and achievement system keep track of progress. Thousands of creatures are ready to fight, above and below ground, and as players level up they can compare themselves on a detailed stats website. The engine Marauroa provides a simple way of creating games on a portable and robust server architecture. Marauroa manages the client server communication and provides an object orientated view of the world for game developers. It handles database access in a transparent way to store player accounts, character progress and the state of the world

NullSAF is a game engine written in Java with features as creating terrain maps and navigation meshes from bitmaps, defining different type of units, sensors, guns, missiles, AI for movement, pathfinding and targetting and simulation of bullets and animated explosions. I learned a lot from it and used it to test new concepts in AI and wargaming. Maybe it can inspire you or you want to really improve it to build your own wargame or serious game. Think of it as Robocode, but then with a far more serious implementation of CGFs and AI.

The original EVOlution RTS seems to be not active (https://sourceforge.net/projects/evolution-rts/?source=directory, last updated on 30th of December, 2010). Thus, this project is to continue the goal of the original EVOlution RTS - To create a game incorporating cells. Since I am an unexperienced Java developer, I need someone to help me out. This is the first major project, and I do require a person to help me out. If you are interested, please email me at weien_1999@hotmail.com or my sourceforge email. I have included a TODO file, copied from the original project, but with added stuff to increase the complexity and fun in this game. For now, I will not use any part of the original project. Only at the end, when I am finished with the basics, will I add the server system.

A bare bones RTS game framework. It has networking and replay support, and have some building blocks to build AI agents (discretized path finding in a continous world). Update (2025. Jun): javax.xml.bind.annotation.XmlAccessType was removed from JDKs later than 1.8. So use the project with JDKs from 1.6 to 1.8. Write in the forum if you're interested in running it on a more modern JDK. The demo program's entry point is Dom1Bootstrapper. You can download a runnable demo jar from the files. If your default JDK is higher than 1.8, it won't start on double click. Update (2014. May 9.): Detailed documentation is uploaded (i.e. my thesis). It examines the system from the user's perspective, but includes some internal details too. Of course it has some extra chapters here and there to conform to the format of a thesis. Check it out at the "Files" section (r221). There's also a corresponding src/bin/javadoc bundle there.

The mech platform floats through levels and progresses over time. It differs significantly from traditional Tower Defense or Survival games. One of the game's key features is the fine-tuned balance of hundreds of gameplay parameters, based on player-collected statistics. However, this feature is not yet fully implemented — it requires a server machine, which I currently don’t have due to personal circumstances. If anyone can provide a server machine or a service like Google Virtual Machine, it would be highly useful and greatly appreciated. The game is written in pure Java using a custom engine. A Java developer or designer is welcome to collaborate on the development. As the title suggests, the game is not yet finished, but it is playable. Developed solo over half a year, with 500 KB of source code and AI-generated graphics. As you can see from the screenshots, the game is designed in a pixel art style. One of the planned features is multiplayer. Your feedback is welcomed.
