Ok so Im enjoying the game its a pretty good game - very deep and complex skill tree that allows you to really do many different things and setups I think it is quite good. I really like the way they did the combat - it is a bit slower if you get into melee because it is kindof choreographed but this allows for all those cool slow-mow moves and I like the way it is done not too bad. I have leveled to around level 7 and completed an amount of the inital Zion contact missions to where I have been given additional contacts with the Machines and I think it was Vorringians? , something like that.
Ok on to the main question of my post. What is the difference between these three factions Zion, Machines, Vorringian? Is there any difference aside from whichever you pick you will be enemies with the other two? I keep hearing about some Construct faction? What is that? Also, I am playing on the pvp server Vector. Thank you!
