	If the scouts locate an X-COM base, a final battleship will be deployed and streak directly towards the X-COM base to assault it. If the scouts are destroyed then the aliens may fail in finding the base. The aliens do not directly score from this mission, but the risk of the loss of a base represents a major blow to X-COM.

	Alien forces attempt to construct a ground base somewhere on Earth. Initial waves of UFO's consist of scouts and an excavator who will land to conduct survey and construction work, a final sortie consisting of a supply ship, lab ship and a battleship will arrive within a short window to inaugurate the completion of the base construction while also landing to offload supplies and personal. Completion of this mission deducts 50 points of score, with the base itself deducting 5 points in its region per day.		Alien forces attempt to construct a ground base somewhere on Earth.

	The aliens will conduct reconnaissance work to pinpoint a target site for a terror mission. A fighter and sentry UFO will conduct the initial reconnaissance before a terror ship assists in preparation work. If the recon is completed a final terror ship will be launched with the terror forces onboard, and will head straight for the target city. Interception of the final terror ship will prevent the terror attack. Completion of this mission deducts 100 points of score, in addition to the ~2000 score deduction if the terror mission is a success for the aliens.

			Alien Terror Missions starting from Alien Bases will send out no scout ships. A Terror Ship will be the only scout before a sudden attack, those can stack up at the end of the month.

	A highly complicated mission intended by the aliens to force a council nation to withdraw all political and economic support from X-COM. A small task force of scouts and a fighter UFO will lay the initial groundwork by conducting reconnaissance sorties, once completed a large contingent of UFOs will rapidly arrive within the target country, starting with a sentry UFO and ending with a battleship. Upon completion the target nation will withdraw from the X-COM project, confer a negative 1,500 score at the end of the month, and see the construction of an alien base within the nation's borders.
