AGE OF ORIGINS - Classic Tower Defense Level 13! 3 Stars! Pro Tips!

I use the same setup on both sides of the map, starting the level with (in order):
Rocket Turret (L2)
EMP (L2)
Laser (L2)
EMP (L1)
Laser (L1)
I found that upgrading anything to level 3 at the beginning ultimately allows zombies to pass through, so it’s best to spread out your firepower and keep the Zombies constantly slowed down.
Second, I prefer to start building Level 3 Laser Towers in the inside lane starting halfway into Wave 3 or so, since at Level 3 they have the range to hit the Zombies on the outside lane, thus creating a situation in which the Zombies will have to face the same lasers twice, if they manage to survive the first exposure. I upgrade the inner lane lasers to Level 3 before upgrading the outer Lasers to Level 3. You can also put an EMP Tower in the inner lane if you want; I prefer just adding more Laser power just for the fun of it.
Happy Zombie slaying 😊 oh and please be my friend and Subscribe 🙂
