Colossus is a Java clone of Avalon Hill's Titan(tm) boardgame. It allows hotseat play, play versus working but not very strong AI players, and network play. Beside the default Titan board and creatures it includes a number of Variants.

We run a Public Game Server where you can find opponents to play against (best chances to find somebody online is when it is afternoon/evening in the USA).

The readme has more information.      The full docs are here.

Testing Build

At the moment there is no testing build.

Download / Build

If you have Java Web Start installed you can download, install, and play with one click on the Colossus icon on upper left corner of this page.

(Note: Java Web Start will post a security warning, and you'll have to give it permission to access your computer before Colossus will run. This is necessary because Colossus uses files on the local computer for user preferences and save games. If this worries you, feel free to download and inspect the source code.)

You can download for the different releases a zip file (with source, docs, etc.) using the download manager on our SF Colossus project page.

(Follow this link for other stuff hosted on SourceForge, like the mailing lists and bug tracker. Note that we don't use every SF feature.)

Building Tutorials

If you want to build and possibly change the code, you can grab it via Subversion. This will often get you newer code, so it is the preferred method if you want to make changes. Click here for instructions on building Colossus, including installing Eclipse and Subversion. Click here for some video tutorials on installing and using Eclipse and Subversion.
