Mission 90

This level has a two disablers, one near the middle of the level, which covers the bottom area and one at the very top. In between the two is a Gate, which is hidden by a dimensional anomaly. You should destroy the bottom disabler before the Elite Overlord arrives.

It is possible to stand on the floor and use a super Not-A-Shoryuken to destroy the lower platform. The 9-inch Waste Disposal Cannon is also an option, especially if it is upgraded since it will automatically fire when disabled (you can quickly fly over it and destroy it. The Not-A-Shoryuken is also a good option for destroying the Gate.

If you fly to the top of the level you can place your Blaster Turret on the ceiling to destroy the top disabler.

You can use your Death Blossom to destroy these structures too.

The main impediment this level are the advanced fleas. It is easy for them to trap you since you can't use your portal turret while they are touching you and they are invincible when in their frozen state. You must quickly teleport to avoid them and destroy the first disabler. When you are able you need to use the Brain Bomb Decrypter to get rid of them quickly (again, not when frozen).

The Expansion Grenade can buy you some time to destroy the first disabler if you are having a problem.
