Build a Skeleton Key. The only way to get into the underground alien base is to use the appropriate key. The project will be automatically sent to the Engineering department, and we need to collect the right amount of components and start production. In addition to a small amount of cash, we will need: 10x Elerium, 10x Alloys, 1x Outsider Shard and 15 engineers. At this stage of the game we have a problem with the appropriate number of staff: the easiest way to collect their missions while selecting the Alien Abduction or building additional Workshops, as each of them provides us with 5 engineers. After gathering all the necessary key components, we can begin the construction.
Attacking the alien base. This is the only mission in the game that allows us to deal with the enemy within its own complex. Despite a very large area, the task is not too difficult: the base is made up of rooms separated by doors, and aliens are not willing to move on against us. We should put the soldiers at the door, waiting for a new round, then open the switch and eliminate everything that appears in front of our weapons. Carefully check the other corners and go to the next door. Last chamber is slightly larger than the other and contains a Sectoid Commander. During the fight with him, we have to be very vigilant, because he is able to take control of the minds of our children. Top to attack and remove the larger group in one turn without risking a long battle. Courageous players can attempt to capture him alive, which is a much more difficult task. After removing the Sectoid Commander, the mission will be successful.
Making autopsy of the Sectoid Commander or interrogating him (if we captured him alive). Whatever option you choose, we get the opportunity to build Psionic Labs. Although the design is not yet needed us, we should start the construction as soon as possible, because the psionic abilities to greatly facilitate the game.
Conducting research on the project Hyperwave Communication. These studies will allow us to decipher the alien communications between ships. Completion of installation allows you to build Hyperwave Relay. At this point we might be interested in the development of our fleet: soon we will need a strong armed fighter, so it is necessary to invent and build a Firestorm class aircraft and the plasma cannons. It would be useful to build one of each bonuses for the airfight.
Build Hyperwave Relay and use it to scan the sky. Nothing more simple: we start the construction (remember to ensure adequate amounts of power, and free space), after which we go to Mission Control and press the well known button Scan for Activity. With a bit of luck, we can receive a signal from the Overseer class ship.
