TanksDS by sulfyr is multi-player game inspired by games like Tank Wars, Pocket Tanks and Death Tanks. Blast your friends, enemies or foes into pieces – even via LAN and Internet!

Release notes:

Version 0.1 is ready. It works pretty well for two players but i haven’t been able to test it for more players. There are still many things that i wish to implement/improve. Please report any errors you might find. I will try to fix them as soon as possible, but i am very busy with school at the moment.
