Luke Ken 3D Planet Invasion is a free, open-source cosmic retro-futuristic first-person shooter (FPS) game, developed also as a data replacement for the Duke Nukem 3D engine. LK itself, is just raw data for the game engine, these assets are provided for use with compatible engines like EDuke32, JFDuke, and Rednukem or the original DOS version. Luke Ken itself is own game genre features its own unique story, characters, concepts and ideas, while it shares some similarities with Duke Nukem 3D due to the engine, and is not intended to be a direct clone or emulation of the original game. This project is designed to be fully vanilla-compatible, meaning it can be also played using the DOS port version of the Atomic Edition if so desired.
The project is currently in early alpha stage known as AlphaKen. There's no gameplay as of yet, just assets for now. Therefore, we have to manually create the binary file, it's a very time consuming process to do, until some script tools are made to build these game files. We appreciate your understanding as we work towards improving and expanding onwards with the project.
If you like to learn more about the story, click Here. Please beware it is subject to change over time.
Luke Ken 3D consists of game data only, you'll need to download a compatible engine separately. There are several options to choose from, including RetroDuke, xDuke, EDuke32, JFDuke, and Rednukem.
Please note that not all source ports may work seamlessly with this GRP file (Game Resource Package). For example, EDuke32 based source ports only read hashes, which may require to create a .groupinfo text file to define all the hashes for it to read. Hopefully, down the line, this issue can be resolved in the future.
First download the GRP (Game Resource Package) file Here
For EDuke32:
- Extract the lukeken.grp and LK.grpinfo to your eduke32 source port folder.
- Run the executable file of EDuke32.
- Have fun!
Legacy way:
- Extract the lukeken.grp file to your source port folder.
- Rename lukeken.grp to duke3d.grp.
- Run the executable file of your chosen source port.
- Have fun!
It does may vary on somethings like mods, Mostly maps should work just fine. We will try to be faithful for compatibility as possible thats our goal. If you like to check on what source port was previously tested click Here find out more info.
