Hostile forces will gain entry to the base via facilities which open out to the cityscape: the Access Lift and Vehicle Repair Bays. As a battlescape mission progresses, a station may be so significantly damaged that the lower section becomes a crater from multiple large explosions, blocking all movement for all ground-based entities. More than three, the active stations are randomly chosen at mission start. A single base is limited to using three security stations at any one time. Using Security Stations is vital to limit the invaders chance to 'explore' your base for vunerable personel and damage to facilities. Large open areas surrounding a centrally positioned access lift will be more difficult to defend (limited effectiveness and cover of security stations) than a layout with an access lift located in an isolated area or single corridor. LayoutÄisregarding the Cityscape aspect of location and building type, the layout of the corridors surrounding the Access Lift determines the ease of defending the base, and its most suitable operational objective. Hoods are hoodlums, thugs, junkies, criminals, hustlers, homeless bums, hookers, drug dealers, pimps, gang-bangers, street trash, hooligans, vandals, goons, villians, punks, someone named ester, crooks, mobsters, bandits, etc. Mega-Primus organisations will use Corporate Hoods instead of their own Guards.
Any organisation attempting an base assault will use their own security forces.A defensive layout of security stations and facilities will reduce X-Com losses, if any. Hostile organisations will attempt to destroy an X-Com base without any warning! There is no way to stop such action.The larger the craft, the larger the infiltration force! The infestation squad will be similar to the aliens typically aboard the type of UFO. Aliens will be inserted by a UFO hovering above the home-cell in the same fashion as any other infiltration attempt.If vehicle repair bays are present, invaders will also appear within. The main entry into a base will be through the access lift. If all your units are neutralised (panicked, stunned, mind-controlled, killed, or escaped), the mission is a failure and the base is destroyed, including the available 'base slot'. Agents and any technical personel will come under attack. An X-com base targeted for destruction by any hostile ground force will immediately start a battlescape Base Defense mission.
