The patch, dubbed "Hydrophobia Pure," will do everything from remap the game's controls, address A.I. behavior, "improved" graphics and physics, and add "more realistic character water resistance."

Hydrophobia will also receive a new climbing system, cutscenes have been adjusted for length, and just about anything else you could think about the game has been "enhanced" or "improved." The patch notes can be found after the jump.

Those new to the experience can now dive into Hydrophobia at a discounted price of 800MS Points ($10), down from the game's original $15 price-tag. The game's demo will also be "enhanced" and extended, giving players more time to try the game for themselves.

It's great if a developer takes a few cues from its audience and makes a few changes to enhance the experience, but the laundry list of fixes for Hydrophobia makes me feel like I paid $15 to be a part of the game's QA team. Which, based on the murky mess the game was originally in, I don't suspect they even had.

The updates made to the XBLA version are expected to appear in the game's eventual release on PC and PS3.
