Battle Tanks is, "a funny battle on your desk.". Choose one of three vehicles and eliminate your enemy using an arsenal of weapons. Original cartoon-like graphics and cool music, "fun and dynamic," and it has different network modes for deathmatch and cooperative style gameplay. I don't believe it has a single player version, yet. The game is open source and available for Linux (source) and Windows. It's a relatively new game (sf.net project was registered in 2006) so there are still some teething issues it seems.
Adonthell, a longstanding open source console RPG engine has seen it's first update in a couple of years - version 0.4.0 alpha 1. The previous version, 0.3.5, is packaged with a small game called Wastes Edge which is one of the few completable open source games with a storyline and is available for every OS known to man. Whilst the new 'development' version doesn't come packaged with a game, it's good to see a project with nearly 10 years of history is not yet ready to be buried by the sands of time.
The developer of Damnation of the Gods (screenshots) has been in touch. When I mentioned this game last time, a commenter pointed out it hadn't been updated in 2 years. Well, the author of DotG dropped me an email:
I am the developer of DotG - And believe me - did I get a boost from
seeing your post on the freegamer blog!
The problem with DotG right now is the graphics - When I did begin coding on DotG I did it using graphics from the Dungeon Master Java project ... So I put together something - and released (with permission from the graphics artists). Later I got a mail which said something to effect that I couldn't use the graphics any longer (or at least parts of it). Now (quite some time later I started coding again - had completely forgotten about that "small" detail ;) - And then I remembered... However I haven't checked on which parts I can use, and which I cannot - So I think - perhaps it is better to start from scratch and try to get ahold of graphics-artists that can imagine releasing stuff for DotG under an completely open license...
So - the code is out there (GPL'd), but i have no graphics that can go
with it (Just minor stuffs). What I would like to do now is get graphics for my project (prefferable GPL'd) and release all of DotG under GPL or similar license. (I am a Debian user nowadays.. ;)
Dungeon Master Java is another DM clone available from the forums on www.dungeon-master.com - which has a few other free complete DM clones there although they don't seem to be open source.
