National Geographic‘s TV series, Doomsday Preppers, is a documentary series about people preparing for the end of the world. Last November G5 Entertainment launched an incredibly fun video game tie-in, by the same name and today they’re lunching a major update of this fan favorite.

What’s new in version 1.1:

• Prepper management reworked — It’s easier to manage preppers skills now.
• Daily rewards — get rewarded just for checking into the game every day.
• Territory bonuses — Build new floors to collect bonuses that are buried in the ground.
• Loading hints — Receive game tips and tricks while it’s loading.

Available now on the App Store, Doomsday Preppers is the incredibly addictive time management sim where you’re digging down an elaborate bunker, crafting sub-floors dedicated to security, shelter, recreation, crafting, food processing and science. Preppers line up on the surface, ready to descend the elevator and be assigned to a task.
