Bos Wars is a real-time strategy game, following the style of the classic strategy games such as Age of Empires but set in a futuristic atmosphere. The game has been created under an open-source license with a whole developer community behind it constantly upgrading and improving it. Their main objective is to create a completely original and fun open-source RTS adventure.
Bos Wars features two campaigns (one of them, a tutorial), more than 20 missions, support for multiplayer mode to play against human opponents over LAN or the Internet, a map editor and a bunch of different war vehicles and soldiers to battle for victory. Of course, you will also have to take care of resources, gathering as much of them as you can.
