Tower Dominion | Runway Challenge | Iron Dragoons (1st Attempt)

Hi guys, a NEW challenge we got ourselves called the "Runway Challenge". It's an interesting one where you attempt to create a long runway for the enemy units. Please leave a like and subscribe if you enjoyed this! The rules are as follows: 1) You can only build a zone expansion that has 1 entry point. 2) Remain only in the 2 runways. 3) Always come back to the main runway without leaving any gaps.
