Build a core where indicated. Move your frame as far as you can before building another core on the second flattened position. Then build a second on this island and build a core by the portal. This will trigger a level end.

Build cores around your base and keep the shield up until the spiral charges.

Build a transmitter where indicated, continue to build them until you get to the first two collectors. Move you buildmasters as you are building so it gets built more quickly.

First destroy the enemy base on your island then you will need strafers to get across the void. Create enough of these to travel across the void and then convert to rockers to destroy the enemy base.

Build a laser turret near your frame, then at the ends of your lines of cores. Next make sure there is at least one turret in range of all your cores so they are all protected. Keep building as the attacks become fiercer as the level progresses. By the end of the level I had eight around my frame and three for each of the cores at the end of a line and one for every other core.

Start by building cores around your base and build a laser lab. Build two laser turrets for each of the cores. Then build a rocket lab and upgrade it so you can build rocket turrets. Build them especially where ever the big floaty blobs attack as these are the most damaging. If you do not have enough defences put your shield up over the core to protect it. Build towards the four positions keeping good defences. The location of the alpha portal will then be shown.

This is the first level where you face a human opposition. Start by flattening by you base. Build a laser lab, officer plant and technician plant. Then build a transmitter to get to the first howitzer. Build a core and laser turrets near it. From this point onwards keep and eye out for enemy squads destroying the howitzers. Build another transmitter to get to the howitzer nearest your first captured one, move your buildmasters to make this quicker and don't forget to protect them. Build more transmitters to get to the next howitzers and the plant. While you do this get a sniper squad to fend off their squad.

Upgrade your laser lab and add an officer and two technicians to your squad before converting to scummers. Then head straight for the enemies frame. Then build subterra chasers and move your brigadiers and build masters towards the end of your base nearest the enemy as they will send a team of scummers near the beginning of the level. Build another command centre and create a squad of 5 scummers. As soon as these are done move them towards the enemy frame. Upgrade your rocket lab at the same time, and build a large number of rocket and laser turrets to defend against their wargon tanks. Once your first squad is destroyed create another and move it towards the enemy frame.

This level is quite difficult if not done well. As soon as possible try to capture their cores by building one near them and raising your shield. First capture the cores on your right and then try to capture the bomb lab to prevent them building howitzers. You can disassemble the labs to give you more energy. Keep taking over their cores to help you have enough energy to charge your spiral. Watch out for the enemy doing the same to you. After a long battle you should have your spiral charged and finish the level.
