Oh, there is depth in the tactics and teamwork unlike halo(which is just for little boys anyway).
The movement alone is takes awhile to learn, clamping to surfaces ect. Not to mention thinking in 3d. They added tutorials now which will help new ppl.
This game will grow into something great i believe. It did really need these maps which will help a lot.
Everyone should try it, it is something very different from anything else out there.
