The best mechanic introduced in the third gen, hands down. Sometimes I wish I still had MH3U...

I took to underwater combat like a bass. I fail to understand why so many people had trouble adjusting to it... including my best friend who has played since the very first game on PS2. I poked fun at him a lot online... XD

Really wish the 4th Gen had continued giving us more awesome underwater combat, but given all the other new stuff they focused on, I can understand why it was cut. I just hope they bring it back at some point in the 5th Gen titles.

It would be great to fight Nakarkos, Shen Gaoren & Mizustune beneath the waves one day.
