The world of Hydrophobia is fraught with peril, and we’re here to help you survive it. Taking control of systems engineer Kate Wilson, players will attempt to navigate the massive Queen of the World, a luxury ocean liner the size of a small city. When the ship is sabotaged by terrorists, water pours in from all sides, making escape all but impossible.
Designer Dark Energy Digital is justifiably proud of their game engine, which showcases water-rendering technology that goes above and beyond anything heretofore offered in gaming. Depending on how you manipulate your environment, the torrents of H2O will be either your all or your enemy.
Survival horror games (like Hydrophobia) are notoriously tricky and unforgiving, so there’s no shame in consulting a walkthrough for those particularly frustrating passages of play. Check back on release day for a comprehensive, step-by-step walkthrough.
