Globulation2

Globulation 2 is an innovative free real-time strategy game. It reduces micro-management by automatically assigning tasks to units. The player chooses the number of units they want to assign to various tasks, and the units will do their best to satisfy the requests. This allows the user to manage more units and focus on strategies rather than individual units' jobs. It can be played by a single player, over LAN or the internet.
