Zombies, Climb!

You hear La Paz is zom free, and Maxine wants to conduct an experiment - presumably to investigate whether high altitude has any effect on the undead.

Tempers fray up the mountain as Runner 6 continues to infuriate Runner 4, despite the doctor's insistence that they are secretly in love.

Sam puts an end to their bickering as he spots a zombie Mount Rushmore taking shape on the cliff. Its eccentric-looking sculptor pops up beside you.

The artist explains the meaning behind her work; she is making a monument for the future to allow our successors to work out what destroyed the human race.

You are all temporarily deafened as the rocks begin to crumble and fall; the dynamite has started an avalanche and your only safe route is up.

Sam encourages you to speed up, but Runner 4 has twisted her ankle. Much to Maxine's delight, ever-gallant Runner 6 picks her up to carry her to safety.
