After XCOM satellites picked up an alien craft over Colorado (probably over Denver, you know?) a Raven was scrambled for an intercept. After interecept the Raven downed the alien ship which then crash landed in the Colorado wilderness.
Almost before the craft hit the ground, the Earth Monkey Strike Team was scrambled and assigned to the site. the objectives of Operation Brutal Stranger – survey the site, eliminate hostiles and gather alien technology. Assigned to the mission were the following XCOM Agents, Niedzwiecki, Roberts, Hughes and the newly healed Squaddie Norris.
Upon landing the team was able to locate the craft easily and found it relatively intact. While closing distance to the craft, Squaddie Norris and Hughes reported a new, hostile alien life form comprised almost entirely of energy. The creature was within the ship and aware of the team. As the squad moved into position another two sectoids were reported within the vehicle.
