its a good game overall, but its not worth your money, with all its glitches... and only 3 factions, had some flaws.
campaign-you start out as the humans, weak and stuff, then you the little blue guys, then the hierarchy, then the masasi, now ill give you a little faction overveiw
humans- only available in 2 missions and cannot be used in skirmiah
blue guys- cant remember name, but these guys are infantry killers! they got some decent infantry but theyre very fragile
hierarchy- a VERY powerful faction, they get huge walkers that you can build addons onto (thats what i love about petroglyph!) like the one on the game cover for example =D
Masasi- these guys control light and dark matter, and all their units do different things depending on the matter type your switched to, when you switch it affects all units and cant be done invidually, VERY powerful faction, my favorite -D like 2 factions in 1
thats all the factions!... wow
