One of the most innovative games we've seen in Second Life is the limited-time "scavenger adventure" game "Horror Night." Grab your free HUD when you arrive and then seek-to-find the hidden items to collect them all and complete your quest. Once you do, you'll get a special item that you'll use to collect your reward and solve the mystery.
While scavenger hunts are in abundance in SL, "Horror Night" employs some innovative techniques to assume control of your camera during triggered "events" in your journey. There are scares aplenty in this fun adventure, which runs through the end of August.
Visit the developer's website to find more info on this game and the backstory-- but be sure to use Google Translate since it is in Japanese.
