The gameplay is similar to the earlier games in the "Resident Evil" series, to the extent of being labelled a "clone", although there are some additions like a dart gun as a secondary weapon, used to sedate most enemies (mainly, zombie-like "vampires") and then sprinkle "white water" on them to restore their humanity, instead of simply killing all enemies that approach the player (which can also be done). This encourages the player to use a wide variety of fighting techniques if they want to "save" the enemies. As the game advances, more and more creatures appear (whose origins are not that well explained until late in the game), such as giant vampire bats, werewolf-like creatures, giant humanoid mantis-like insects, giant frog mutants (which are similar to the hunters of "Resident Evil"), and purple blobs. The dart gun does not work on these types of enemies.
