Killzone General

[Baptized_Soviet]

Just got the killzone 3 mulitplayer only version, first killzone game and first fps game on the ps3 (just got a ps3 two weeks ago, my first console after ps2) and I've been having lots of fun with it. But I have a few questions:

1. What are those enormous walking mech warriors that kill everything in their path on the very big map with the jetpacks? How do you deploy one? But most importantly, how do you kill it??? 

2. How comes sometimes enemies names above their head flash orange?

3. What game mode has the most players, as well as which reason has the most players? Europe or North America?

Thanks for any helpful answers

1.they're exo suits-mechs..killed by 1 shot sniper rifle to pilot,or rocket launcher or wasp minigun stationed at tsa's-engineers must fix them before you can use. 2.happens when you ads-aim down sight. 3.warzone is 24 max so 12v12 and I'm going to say north America...bigger mass of land should mean more cities means more people. Your welcome.
