Challenge Mode

Auto replant.png This article is a stub.
The article does not cover enough information about the topic. You can help by expanding it.

Challenge Mode is a gauntlet of scenarios (12 per region, totaling to 180 once all regions get challenges) in which you make a blueprint that adheres to special rules (varies between challenges) to defeat waves upon waves upon enemies. Successful completion of a challenge will give you a reward which may come as a module or something that would help influence gameplay.

There are 2 modes to challenges: Normal Mode NORMAL MODE, and Hard Mode HARD MODE.

Hard Mode imposes extra restrictions to increase the difficulty on top of the restrictions from Normal Mode, such as:

  • All challenges have double the required amount of waves needed for completion.
  • All challenges disable Town-related bonuses from various sources (Museum, Arcade, Shipyard, etc.).
