Strategy:
Towers / Skills Needed: Ballista + Explosive Shot
Tower Levels Needed: Archers Excellent-1-30, Barracks (probably possible with Ordinary-20)
Use Magics where all of the paths meet if the enemies start to overwhelm you there.
Initial Setup:
Move barracks rally point closer to where all of the paths meet as show in the Picture.
place all 4 of your heroes slightly below where all of the paths meet.
Final Setup:
Always keep heroes below the place where the paths meet. Back the heroes closer to the exit if needed to keep them alive.
Upgrade the Original Archer to Ballista + 3 star Explosive Shot
When you have some extra goods, sell the top left barrack and replace it with an archer. Upgrade this new archer to Ballista + 3 star Explosive shot.
When you have some extra goods, sell the top right barrack and replace it with an archer. Upgrade this new archer to Ballista + 3 star Explosive Shot.
If you have extra goods after this, build an archer in the top left corner as shown in the pic.
Only if needed, upgrade the remaining 2 barracks.
This might take some luck. Dont worry if you can't get it on the first try.
If you still can't get it, upgrade heroes. Gunnar is a very good hero for this level.
