Kingdom Rush Frontiers is getting a new endless challenge mode three weeks after Hulking Rage was released for Origins. Ironhide Game Studio made the announcement via Facebook on Thursday. The new campaign titled "Temple of Ethereal Evil" will feature "endless alien spawns and their brainwashed tribal allies." The update will also include a new hero for players to use. It is unknown if the hero will be free or available as in-app purchase.
This is the second endless challenge Ironhide has released for Frontiers and its first update of 2015. Both Kingdom Rush and Origins were updated with new levels and heroes in February.
Temple of Ethereal Evil will be available on Wednesday, March 18. Kingdom Rush is a popular tower defense series available for the iPod touch, iPhone and iPad. All three games are available on the App Store starting at $0.99.
