The second "Half-Life" expansion pack, "Half-Life: Blue Shift", was again developed by Gearbox Software and announced by its publisher, Sierra Entertainment, on August 30, 2000. Sierra intended to release "Blue Shift" for the Dreamcast, and it was set to include higher detail models and textures that were double the polygon count of the models from "Half-Life". However, after several months of delays, Sierra terminated development on the Dreamcast version of "Blue Shift" on June 16, 2001, and the company instead released "Blue Shift" for the PC on June 12, 2001. Afterward, Gearbox began working on a "Half-Life" game for the PlayStation 2. The game, "Decay", was showcased at E3 2001, where Gearbox demonstrated the game's use of new model sets, which were around twice as detailed as those in "Blue Shift".
