Challenge Mode

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, and 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.).

UPDATE: Page needs to include Hard Mode Challenges https://github.com/Blueturbo47/bluecats-PerfectTower2-comp./blob/main/Challenges/Hardmode/Pre%20Era/README.md

Note: If the solutions on this page do not work for you, your Laboratory and Museum powerstone Boosts may not be sufficient.

If you have alternate solutions to Challenges that are not here, please use the Discussion page or create another solution box instead of editing an existing solution with your own solution.
