We are sorry to tell you that development on Undead Legions 2 has stopped. It may not seem so, but making a game like this with different types of game elements (tower defense, looting, arcade-style combat, action rpg elements) requires a decent amount of daily work and many hours of balancing and playtesting even for mediocre changes and/or add-ons. Although receiving a lot of positive feedback, sales have been very weak so far, so we finally decided to discontinue this title.
In its current state, Undead Legions II is already a very cool and well balanced game . You can have good fun with it for at least a couple of hours. It has bosses, a co-op mode, quite a bunch of items to collect, and a good set of different skills and characters to try out.
