The leviathan. It was just plain fun. It reminded me alot of the giant lake monster from Resident Evil 4.

Haha I actually thought the Skorge fight was lame, the worst out of both games, even. Running around in circles and mashing the B button every 45 seconds was really REALLY dull. I was let down by how poorly they did the initial fight, and the Reaver racing was about 10 seconds of "Oh my god I'm riding a reaver" and 10 minutes of "I'm actually just moving side to side on a Troika with the background changing every so often".

Although, I can see why people may have liked it, just because of how deep into the story you were at this point.

MY favorite "boss battle", or fight rather, was racing against the Locust controlled Rig with Dizzy. On Insane difficulty, this was particularly intense for me, and quite a rush when my last ammo clip landed the killing blow. The explosion, the oh so beautiful victory fireworks created from the destruction of the Rig rewarded me with a sense of accomplishment as well as the visual satisfaction of ending the lives of those Locust.

mine was against the lambent brumak it was a challenging battle
