How come Gorea v2. Is so hard even with the omega cannon?

Really, he isn't. At least to me. I beat him easily on my first try. I guess what you have to do is memorize where he keeps on appearing. And get the healths as you go. And if you didn't look at the cheats, I wrote a complete walkthrough on how to beat Gorea 2:

This is for all of you who are having trouble with beating Gorea 2. First things first when you get there, you should scan Gorea 2 (that's if you never did). Then go straight to the bottom floor by turning around and going down the so-called steps, or you can just jump down. Right before you reach the bottom (if you jump), double tap the screen to jump before you hit the bottom , so you don't get damaged. A few seconds later, a gunship message will appear saying that Gorea 2 is invincible to every weapon except for the Omega Cannon. That's right. The ultimate power is right behind that barrier. Now go collect the ultimate power! Once you do, use the Omega Cannon to shoot Gorea 2. Watch out for his beams and meteors. Right after you get the Omega Cannon, Gorea 2 will be right above your head. So move over and shoot him. He will screech, then shake his head and disappear. Stay there. He will reappear and you can shoot him again. He will do the same thing and you must repeat what I told you. This time when he disappears, he won't reappear there. So jump up onto the so-called stairs and get the health if you like, but immediately go onto the jumping pad to get to the top because there will be meteors chasing you. You can destroy those meteors and get a health pack, but it's a waste of time. So move on and keep on jumping from jump pad to jump pad until you get to the top. Once your on the top, quickly turn around because Gorea 2 will be where you just jumped from. Shoot him and he will disappear yet to reappear on another side on the top floor. Look around (don't go down!) for Gorea 2 until you find him shoot him twice and he will disappear. Do this once more, I think, and then he will go down either on the mid-floor or the bottom floor. I don't know where he would be, because this part is always random. After you shoot him (make sure his head shakes so you know when he's going to disappear), he will go back to the top floor. Once again, jump on the jumping pads until you get to the top floor. Shoot him twice and he will disappear. This should be your last round, unless you missed him once. Shott him twice again and you should have beaten the game! Now the sound test was unlocked! Go to the options page to listen to them. Wasn't that easy? Enjoy the video and.....do whatever else you want to do!

Hope this helped!

Gorea v2 is the hardest because he is at his ultimate form and he has the ultimate power and he is absorbing the power.The only way to beat Gorea is by hitting him with the omega cannon fast and if you keep missing him theres a more likely chance to lose against Gorea.I hope I helped you.
