*peeks in*

I am interested in the 3DS version. I downloaded the demo on the eSHop and...I think I am doing it wrong. I ran around, killed some monsters and found the big guy was supposed to get for the mission. So I begin fighting. I wail away on this monster a good 15 minutes. I have no bar to show if I am actually hurting him. I gave up eventually (about 25-30 minutes) because had no idea how to kill it. Is there a trick I am missing? Always thought this series looked fun, but wanted to better understand it before buying an entry.

If there's a beginner's or novice guide be appreciated.

You can fight as many as surround you.  So if 3-4 Jaggi surround you and you are aiming right then you can at least hit 2-3 of them at the same time.  Later on in MH3 (Wii) you might have two major boss monsters in the same area on the map.  You gotta be careful when that happens.

No trick, there simply isn't any life bar or anything. Just keep on attacking to lower its health (go for the Ice-bunny thing) and eventually you should see it getting tired. It's ears will fall down and as such it will lose balance when it charges, for example. The most common sign of a monster being near-death is it limping, however. When that happens you're mere seconds away from victory!

That's one of the fun things about the game. The enemy health bar is invisible. You just keep attacking it until it dies lol. There are also signs to let you know that its near death like limping.

of course :) and I also just confirmed that wifi just sucks. for testing sake, I started with wifi, and the time was 3 hour something, then changed back to usb ethernet and viola, 1hour25. they should have at least given us a 5ghz option, 2.4 just blows these days.

or let me hook up a ralink wireless adapter to it for 5ghz n at least, drivers pls nintendo!

I was lucky to get far enough on MH Tri to see two enemy bosses, but will there be any quest that let you take two on?  A Rathalos and a Rathian would be overkill.

oh yes, you will get combos like that even on very hard missions, they are fucking great fun.

I should have kept playing it lol. Using a bowgun I would probably run out of ammo, but that rarely happens. Fighting two bosses can really test your skill and have you sweating at the same time.

Yeah, the ice bunny.  So, it is normal to take a half hour to kill him then?   Is this a game can play with others?  I think that would help me a lot.

Oh yeah, half an hour is most regular, the key is to just keep going and you will see what difference you're making. And it is a game which can be played with others, and is best experienced when you do that. Sadly the 3DS version only has local play, so the online talk in this thread and the OP relates to the Wii U version only.
