i whant to now how too figth stuff

Combat's not in the Combine yet, unfortunately. However, you can brawl with brawler type NPCs.

Is there a way to earn XP fighting the brawler NPCs?

random 1 - 5 XP per brawl won.

I was fighting a brawler, but after every time I hit him, his HP restored back to full 12/12, while mine kept going down and not replenishing that fast, so I had to run away? Why do NPCs get to heal their damage so fast?

bug

Ok thanks... so unless I can kill them with a single hit, I'm never gonna win the XP for fighting them! Oh well, for now I guess I'll just keep walking around in circles to earn XP! LOL

it's only brawling, you can't kill them (nor can they kill you). Once you get them down to 1 HP they give up and you win.

is there ship to ship combat or dogfights yet??

No, there's no other space or ground combat beyond brawling.

With the Combine, you have to be patient and willing to wait. Some people have been here before there was even space travel.

no way that most of been torure to them cant wait tell combats out thow

You and the rest of us. I challenge you to a duel in.... 2008?

lol thats funny
