Guild Wars 2

Hello everyone.

My name is Kruno, I have just started playing Guild Wars 2 on server Baruch Bay.
I love this game, but as in every other MMORPG, I suck first few weeks.

Today, I was leveling my first Sylvari character and I got stuck at a level 4 (probably campaign) quest, named Loved and Lost. Here is a picture of it http://www2.picturepush.com/photo/a/11485385/1024/Anonymous/gw002.jpg .

It says that I need to kill the undead but I can’t do any damage as they all are invulnerable and I went to wikia, it says only distract their attention and kill them, but I can’t.

Can anyone tell me what I need to do and is this a bug or I am just failing on something? Basically, what should I do?

Thank you all, and hope to see some of ya in game.

The green circle on the map is too big. at the bottom you see a skull. That is the NPC that needs defending from the invading waves of undead. It is also where you activated the turrets. So thats where you have to fight the undead. if you move too far out you get this situation.

So yes it is a bug, but a minor one. Stay foot and you will win

Thank you so much mate, it helped and worked.
