Geologist Kyle returned to Scott and his team and told them about the gunshots and the missing geologists. They immediately went to the caves and set up camp outside. Walters set up a life scanner and Scott, Professor Kyle and most of the troops went into the caves. There they rested when Professor Kyle tripped. They heard Walters speak to them through the intercom, saying the wounded party (Baines and Collis) had gone off the scanner — dead — and an alien had been spotted in the lower caves. Scott sent Sergeant Mitchell, Bailey and Carter to investigate. However, they were later killed after they found the remains of Baines and Collis.
