One of Monster Hunter Tri's hardest monsters, the Alatreon, is quite the challenge for even the most expereinced hunters. You can learn his pattern, but it takes some skill to do it in under 15 minutes. The video above is something you and your friends can try out pretty easily, making the quest end in under 45 seconds. It might look cheap and easy, but you'll need the right gear, felyne skills, plenty of bomb material, coordination with your team, and a little luck with a bowgunner paralyzing him.

If you're having trouble getting Skypiercers from the Alatreon, this is something you may want to try. You need to break his horns for a chance to get one in the rewards, and this bombing technique made mince work of 'em.

Thanks for the tip Moises!
