Frictional Games has announced the relaunch of its first-person horror trilogy Penumbra as a single collection that will be on sale for US$5 this weekend, after which time it will sell for $20. The Penumbra series – Overture, Black Plague, and Requiem – features a storyline set below ground in Greenland, where main character Philip discovers a hatch leading to a place that may explain how and when his father vanished.
Penumbra's graphics engine sports a similar look and feel to id Software's Doom 3 engine, except players don't mow down hideous monsters with various types of weaponry. Instead, they explore the environment, picking up objects that may help them as they solve puzzles and eventually unravel a mystery. Enemies abound, but Philip must typically sneak around them to stay alive – the environment's few weapons, such as a wrench, don't usually do much other than anger them.
System requirements call for Mac OS X version 10.4, a 2GHz processor, 1GB RAM, 2GB of hard drive space, and a minimum ATI Radeon 9600 or Nvidia GeForce 4 video card. The GeForce 4MX video card is not supported.
