Even though its essentially C&C 3 Tiberium Wars , theres so much diversity between factions
and, each faction gets it's own unique units too
The Steel Talons don't have access to tanks, instead they use walkers
And, Reaper 17 faction don't use aircraft, but their ground units are more effective
There's also a few different maps for Multi-Player, and the build interface is alot more refined too
You should pick this up asap
