Slender: The Arrival, Blood of the Werewolf hit Steam at a 20% discount

Blood of the Werewolf and Slender: The Arrival are now available on Steam, bringing a batch of Greenlight-approved horror to this week's Halloween festivities.

Slender: The Arrival is a reimagining of the first-person indie freeware hit Slender: The Eight Pages, developed by Blue Isle Studios in collaboration with Slender mythos creator Eric "Victor Surge" Knudson. The Arrival expands on the original game's premise with new narrative elements and improved graphics while upping the horror quotient with Oculus Rift support.

In the 2D platformer Blood of the Werewolf, players assume the role of a part-time mother and full-time werewolf as she quests to rescue her kidnapped child from a gang of movie-inspired monsters. Blood of the Werewolf, coincidentally, was part of this month's collaborative Not on Steam Sale. As of today, it's not not on Steam.

Both games are available for 20 percent off of their regular prices through November 4.
