Neptune is a single-player modification for Half-Life 2, taking place entirely outside the mother game's universe. Set primarily onboard a mysterious and desolate cruise liner, floating in the middle of the Atlantic Ocean, Neptune allows the player to slowly unravel the dark and disturbing past of the ship as he/she explores its once-grand rooms, corridors, concert halls, restaurants, bars and maintenance areas. Taking influence from games such as System Shock 2, BioShock, Thief: Deadly Shadows and Silent Hill, Neptune is an atmospheric, narrative-driven, horror-based shooter; an exercise in videogame storytelling and tense level design. It is expected to be released in Q3 2009.
In-game footage of Neptune. Taken from an early part of the game, which sees you attempting to restore power to the bowels of the ship, and set the engines in motion. But is someone trying to thwart your progress...?
Apologies for the rubbish quality. The game slowed down practically to a halt every time I tried to capture at high-definition, and even when I did manage, the file size was gargantuan. This will have to do for now.
