Vampire Rain

Vampire Rain is a stealth game similar in nature to the Splinter Cell or Metal Gear series. Players are tasked with navigating their character through city streets, while avoiding the vampire enemies that patrol the streets disguised as ordinary human citizens. Players often have to take alternate routes, such as climbing onto rooftops or through alleys, to avoid enemy encounters. The only way to effectively fight them is through situations where the players can fight a nightwalker in a 1:1 scenario.

Unlike most stealth-action games, Vampire Rain places heavy emphasis on pure stealth. Enemies are extremely fast and can kill the player in two hits; the first hit usually immobilizes the player, giving the vampire sufficient time to land a second, killing blow. Additionally, for the first third of the game, players lack any weaponry that can kill vampires effectively without spending a large amount of ammunition. In effect, most attempts to initiate combat generally result in the player's death.

Vampires, known as "nightwalkers", were found to be responsible for the disappearances of civilians in the United States and in other countries. The American Information Bureau (AIB) raises a black ops special forces unit, which is deployed to the streets of Los Angeles.

Throughout the game, John Lloyd is haunted by the vision of a young girl, whom he saved in a previous mission when nightwalkers launched a raid on the Office of Disease Control (ODC). Their attack killed almost all the ODC personnel and special forces operators sent to secure/retake the ODC building. Eventually he finds out that his team leader has also seen her.

In November 2006, AQ Interactive announced an early purchase bonus of a clip for anyone who preorders the game. AQ Interactive held a promotional event on January 2007 in Nihonbashi, Akihabara and Osaka where participants are given game-based clear file folders for free.

In February 2007, AQ Interactive reported the launch of two demo stages through Xbox Live Marketplace for free.

The game received "generally unfavorable" reviews on both platforms according to the review aggregation website Metacritic.

The reviews criticized Vampire Rain's enemy AI, controls, health meters for both the protagonist and enemies, and multiplayer modes. The game was also criticized for having elements derived from Metal Gear Solid and Splinter Cell but with much less appeal. The game was criticized for being too hard and for the linear level design. However, the game was complimented for its eerie music.
