Description:

Tiberium Nest is a huge 4-player, tactical, balanced symmetric map for skirmish play. The home bases are in corners and well protected, but you need to expand relatively early and take control of the map. Choose wisely who you attack and when, because the armies need to travel quite a bit, and an assault may leave your rear exposed. You will need to distribute your armies wisely, and be aware of your opponent's movements.

First one to capture the Tiberium nest in the middle will have a lot of resources, but beware - the middle is open from all sides, so it can be difficult to defend.
