The Underpass

: It seems that the Temple of Saqra was merely the entrance to a vast underground labyrinth, carved into the mountain rock itself! There might just be some truth to the legends that warn about an unspeakable evil here...
: We must head into the maze, for our mission cannot be abandoned. If only the overwhelming darkness were all we had to face...
The Underpass is the 12th level in Kingdom Rush: Frontiers.

===Upgrades and Hero===
Most recommended hero is Alric because of his ability to summon Sand Warriors and to reflect damage. It is best to put him it the end of the path to stop remaining Saurian Nightscales and Saurian Broodguards.
===Towers===
It is ideal to invest in a Battle-Mecha T200 early on in the level because it can devastate the Saurian Broodguards and Saurian Nightscales in the first waves and also along side the mech put some Mage and Archer towers.
