Homebase Storm Shield
Homebase Storm Shield (SSD) occurs throughout the game. It's unique to each player. Every so often (20 or so quests in Canny Valley and Twine Peaks) the player will need to expand their stormshield. This requires either a defence or a new amplifier to be installed. Players must fortify and defend their amplifiers during each SSD. Building changes and progress are saved upon exiting.
When a SSD is completed, the player's next series of quests will be slightly more difficult. Rewards for SSD's include large amount of Hero XP and Mini Llamas.
