The 0 A.D. team have been extremely busy as always to bring us the latest and greatest in open source RTS gaming.
First of all they really need programmers to join in and help, and considering how amazing the project already is I hope others pitch in and help. Go to this thread on their forum to see how to join them.
As for progress, they have been hard at working on their meshes and armature to bring them up to more modern standards. The AI bot is becoming increasingly smart, and now supports saved games!
Their use of the "SpiderMonkey" software has been updated, so it brings with it general performance increases in many areas. That is one of the most common complaints about 0 A.D., so it's good they are working on it.
Lots of new animal models have been made like sharks and tunafish; who doesn't love tuna?
Masses of bug fixes of course.
See their full rundown here. Looks like Alpha 18 is going to be quite something.
