Complex is a free advanced game modification based on Relic Entertainment's Homeworld 2 game engine, free of any business directive, developed with passion and hard work, for experienced RTS players only. In a world of simplified games often under pressure to do well commercially, our challenge has been to create this ambitious project, for those who want more from a modern videogame.

Only who has time, and want to put a lot of efforts in this game will really like it while most of the normal player will get bored by it's "complexity" after some matches.
A mod that has nothing to do with the original HW2, and that make it more complex as the title says.
It is slow paced and and with the introduction of power in 8.2.3 it is even slower than it was before.
