Swarm Assault Level 59 - Vertical Islands

This is not a tough level. You just have a scorpion colony. Start ninja production. Protect the ninjas from neutrals. Once you have 2-3 ninjas, bring them down to the neutral wasp colony. Few steps at a time. Wait for any neutrals to show up and kill them. Walk them through the exact middle so as to avoid spider colony turrets. Once you're near the wasp colony, move all but one ninja a little high because if you attack with multiple ninjas all but one will take unsafe attack points and will die. Also, you need at least 1 other ninja to protect the attacking ninja from emerging neutrals - this is vital. Let one ninja attack the wasp colony safely. Keep the other ninjas in the safe zone, and protecting the attacker. Once the colony is down, kill off emerging neutrals, conquer it.

Protect the wasp colony using the ninjas. Post them just above the wasp colony. Keep an eye on the scorpion colony in the mini-map. Before either Green or Red spiders start approaching from nearby islands, post the ninjas on either side of the home island to kill them off... They may still need a little manual oversight to kill off missiles.

Start producing assaults and couple of paralyzers. Take 2-3 assaults and go left and attack the neutral wasp colony. There is one spot where the assault wasp can safely attack a wasp colony (towards the right of the colony). One wasp will stay alive and continue attacking. The home wasp colony may face attacks from spiders - watch out and take down attackers using assaults of ninjas. Once the neutral colony is down, bring in some assaults and paralyzers to occupy and protect it from intruders and neutrals from the North. Now, start sonic production on both wasp colonies. Wait for build up, watch out for attacks on coloneis, protect units. Once you have enough sonics, go and take down the Green spider colony. You may take over the adjacent beetle and ant colonies too (thought the ant colony may be lost soon to the forces from the North - scorpion colony).
Next colony to take down will be the right wasp colony. You'll need sonics for this. Use sonics again, to take down the Red spiders. Eventually, you'll be using missiles from the spider colonies to take down the scorpions safely.
