About Sanctum Map Pack 1
Sanctum Map Pack 1 adds four levels to the game, set during the alien invasion of Elysion One and its aftermath. In each, you help Skye and her friends or other defenders hold back the aliens while people carry out rescue, reconstruction or evacuation efforts.
The levels
- Aftermath: As reconstruction begins in the overrun Elysion One, Skye and her friends defend what remains of the city from the aliens.
- Aftershock: Earthquakes and increasingly intense aftershocks disrupt reclamation work while aliens swarm the underground facilities. Hold them back as they cut down the bridges.
- Cavern: A rescue operation moves deeper underground, where the aliens are known to venture only so far. You join the battalion tasked with keeping the creatures at bay during the move.
- Slums: Civilians flee by ship from the distant quarters of the Slums, the site of the planet’s original settlement. Defend them as the aliens pursue them.
