The second expansion for Tower Tactics: Liberation! Comes with:

• 1 new game mode: Siege!
  

Build your card collection and keep your morale high to survive as many days as possible in the endless siege!

Buy card packs to grow your collection, build towers in the Crystal Mine to increase your income, visit the Sanctuary to restore your morale, and much more!

At the end of each day, you will face a combat in which after the last wave you'll have to open the gates to unleash an endless wave of enemies! You can close the gates at any time to stop more enemies from appearing, but if you do it too soon you'll lose health and morale! On the other hand, if you survive for more time than needed you'll receive a reward... but don't get too greedy, since even though enemies stop spawning after closing the gates, you still have to deal with the ones that are alive!

• Its own metaprogression! Go up in Siege Level and increase your power for future runs!
  
• 9 classes with unlock challenges!
