Defcon 5 (1995 video game)  Defcon 5 is a single player adventure/first-person shooter video game developed by Millennium Interactive Ltd, a UK-based studio. It was released for MS-DOS in 1995, and ported to PlayStation, Sega Saturn and 3DO Interactive Multiplayer in 1996. The name refers to the condition used to designate normal peacetime military readiness under the DEFCON system, but which is commonly misused in popular fiction to indicate a state of emergency. The game was originally announced under the title "Incoming". As a "cyberneer" working for the fictional Tyron Corporation, the player is tasked with installing an automated defence software at the deep space mining installation named MRP-6F, a large compound located around the top of a crater in which mining operations take place. Its purpose is to defend the mining installation from hostile attack. For this purpose the installation houses six powerful defence turrets installed around the crater, as well as a myriad of support systems for power generation and munitions stores for those armaments. Shortly after his/her arrival at MRP-6F the installation is attacked by an unknown enemy force. The player must face enemy fighters as well as invaders searching the base. The overall goal is to escape the installation with evidence of what has transpired. The game is reminiscent of the System Shock series in terms of gameplay. The player must explore the base to find items which is needed to establish a line of defence and ultimately escape the installation. This involves fighting off the invading enemies by deploying the defence turrets effectively and using the installation's computer terminals (called "VOS terminals") to hinder the intruder's advance. The computer terminals in the game offer an unusual wide range of interaction. Players can use them to remotely control the defence turrets, load ammunition and inspect the turrets for damage and deploy combat droids within the installation's perimeters. Doors can be controlled from the VOS terminals to control access to the installation's different areas. The player can use this capability to lock in enemy forces in parts of the installation. The game also allows the player to fight the invaders by shooting them, but this is discouraged by the fact that new enemies arrive with each passing wave of attacking ships. Also, destroying an enemy greatly degrades the air quality in the immediate area. The computer might even seal doors to polluted areas, sometimes trapping the player. The player can dissolve the pollution by opening doors to adjacent areas, and the pollution levels can be monitored in the VOS terminal's environmental module.' The installation consists of two major towers with seven floors each (the administrative and domestic blocks), three hangars, a service level, six turrets and a control room.
