Blue Shift Unlocked


Blue Shift is an expansion pack for Valve Software's science fiction first-person shooter video game Half-Life. The game was developed by Gearbox Software and published by Sierra Entertainment on June 12, 2001. Blue Shift is the second expansion for Half-Life, originally intended as part of a Dreamcast version of the original game. Although the Dreamcast port was later cancelled, the PC version continued development and was released as a standalone product. The game was released on Steam on August 24, 2005.

As with Gearbox's previous expansion pack Opposing Force, Blue Shift returns to the setting and events of the original game, but portrays the story through the eyes of a security guard, Barney Calhoun, employed by the Black Mesa Research Facility. After a scientific mishap causes Black Mesa to be invaded by aliens, Calhoun must fight his way to safety. The game received mixed although mostly positive reception. Many reviewers were critical of the short length of the game and the lack of new content, although the inclusion of a High Definition pack that upgraded the models and textures in both Blue Shift and the preceding Half-Life games was praised.


Blue Shift is the first game in the Half-Life series to feature consistent interaction with a single non-player character, Dr Rosenberg

As an expansion pack for Half-Life, Blue Shift is a first-person shooter. The overall gameplay of Blue Shift does not significantly differ from that of Half-Life: players are required to navigate through the game's levels, fight hostile non-player characters and solve a variety of puzzles to advance.The game continues Half-Life's methods of an unbroken narrative. The player sees everything through the first person perspective of the protagonist and remains in control of the player character for almost all of the game. Story events are conveyed through the use of scripted sequences rather than cut scenes. Progress through the game's world is continuous; although the game is divided up into chapters, the only significant pauses are when the game needs to load the next part of an environment.

The player battles through the game alone, but is occasionally assisted by friendly non-player characters. Security guards and scientists will occasionally help the player in reaching new areas and convey relevant plot information. Blue Shift also includes a substantial section dedicated to keeping a major character in the story safe from enemy characters, and escorting him to a specific location.A selection of enemies from Half-Life populate the game, including alien creatures such as headcrabs and Vortigaunts. The player also encounters human opponents in the form of a detachment of US Marines who have been sent to eliminate the alien threat and silence any witnesses.As Blue Shift does not elaborate on the storyline in Opposing Force, no enemy characters from the preceding expansion pack appear in the game. Likewise, none of the new weapons introduced in the expansion can be used by the player, they are instead given access to a limited selection of Half-Life's weaponry to defend themselves with in the game.



Blue Shift is set in the same location and timeframe as that of Half-Life, taking place at a remote New Mexico laboratory called the Black Mesa Research Facility. In Half-Life, the player takes on the role of Gordon Freeman, a scientist involved in an accident that opens an inter-dimensional portal to the borderworld of Xen, allowing the alien creatures of Xen to attack the facility. The player guides Freeman in an attempt to escape the facility and close the portal, ultimately traveling to Xen to do so.[7] As in Opposing Force, Blue Shift shows the events of Half-Life from the perspective of a different protagonist. The player assumes the role of Barney Calhoun, a security guard working near the labs where the accident takes place. Calhoun is responsible for the preservation of equipment and materials and the welfare of research personnel, and after the accident plunges Black Mesa into a warzone, he must work with Dr. Rosenberg, a high-ranking scientist involved in the experiment, to evacuate the facility.


Blue Shift begins in a similar manner to Half-Life, as Barney Calhoun rides a tram through the Black Mesa facility to reach his place of work. After reporting for duty, Calhoun is instructed to assist in maintenance on a malfunctioning elevator. As Calhoun finishes repairs, however, Freeman's experiment takes place and results in a "resonance cascade", causing massive damage to the facility and teleporting alien creatures into the base. The elevator is badly damaged and fails, sending Calhoun plummeting into the depths of Black Mesa.

Calhoun regains consciousness at the bottom of the shaft and begins to fight his way to the surface to escape. Emerging near Black Mesa's classification yards, Calhoun learns that a Dr. Rosenberg and his colleagues plan to escape the facility using teleportation technology. After freeing Rosenberg from the captivity of the US Marines detachment sent to silence the facility, Calhoun escorts him to a decommissioned prototype teleportation laboratory, where several Black Mesa employees have already gathered. Rosenberg then teleports Calhoun to the Xen borderworld to calibrate research equipment needed to pinpoint a teleport destination outside of Black Mesa. Upon his return, Rosenberg informs Calhoun that the teleporter's battery power has been exhausted, and contact has been lost with a team sent to acquire a new power cell.

Calhoun travels to the power generators on a lower level to find a fresh power cell while firefights rage between the Marines and the forces of Xen. After returning with a new power cell, Calhoun assists Rosenberg in evacuating the few surviving personnel through the teleporter. Calhoun is the last to enter the portal and as he does so, Marines breach the laboratory and fire on him, causing the teleporter to explode. As a result of the teleporter's destruction, Calhoun enters a "harmonic reflux", causing him to be rapidly teleported to a variety of locations in the facility. At one location, he witnesses Freeman's capture by Marines mid-way through Half-Life, before eventually stabilizing at the intended teleport location with Rosenberg at the outskirts of Black Mesa, where they then escape the facility in a company SUV.


Blue Shift Unlocked

Blue Shift wasn't initially available on Steam like Half-Life and Opposing Force. In August 2005 the Half-Life Improvement Team released a mod that ported the legacy version of Blue Shift to Steam, allowing the player to play it as a fully working mod for HL1 rather than its own stand-alone game. This had the added benefit of letting Blue Shift take advantage of features that had been added to the GoldSrc engine since then, such as detail textures. Almost immediately after, Valve made Blue Shift officially available – but it used its original engine, and suffered from many of the same bugs as the legacy version. A few months later, the porting project was updated, and renamed to Blue Shift: Unlocked.

The game was originally intended to be on Dreamcast, thus using another .bsp format than Half-Life uses. Although the Dreamcast port was later cancelled, but they kept the .bsp files the way they were, which means that the maps are unable to ripent. Blue Shift: Unlocked allows owners of Half-Life and Blue Shift to convert their Blue Shift installation into a Half-Life mod, which means that the map files will be the same .bsp format as the Half-Life maps. Yes, this means that the maps will be able to ripent with Blue Shift: Unlocked. Plus, all bugs that were in v1.0 will be gone as Blue Shift: Unlocked treats Blue Shift as a Half-Life mod.

Blue Shift Coop

"Blue Shift Coop" allows you to play Blue Shift cooperative. It's not recommended to people that hate bugs, since running Blue Shift cooperative is very buggy due Blue Shift was not meant as an online game. Also, Blue Shift uses another bsp format then Half-Life, so nothing in the maps are changed at all. You must have Blue Shift on Steam in order to play Blue Shift Coop, it won't work on Won due to invalid cd key error message. You must also either have an LAN or internet connection.


Attention! For play Blue Shift Unlocked Coop you need Half-Life (not source or not 2)! Install Blue Shift to Half-Life folder, after - install Blue Shift Unlocked to Half-Life folder.
