When they arrive at the mine entrance, they were faced by a large amount of Chasers. Kyle gets heavily hurt and flees into the mine, where he will fall into the big hole with some of them. In this time, Aya fights the enemies off and goes into the mine, too. There she has to cover the hole with a large oak plank. After completing a puzzle in form of an electronic circuit, the gate unlocks and Aya will be attacked by the Blizzard Chaser. Aya defeats the two forms of the beast and finds Kyle's Handgun after the first fight. Furthermore Aya finds the second jumper and finally completes the circuit and can enter the shelter by unlocking the shelter gate by turning a key on No. 9 GOLEM's motorcycle.
The storage room where Aya must solve the puzzle has the only save point that Aya asks if the phone can make outside calls, along with a question to dial to M.I.S.T HQ or not.
