Shield World on Legendary is annoying because you only get one base, and therefore takes a while to get things going! It's very doable as long as you act very quickly to rescue the first group of troops.

My strategy for Mission 10: Shield World

The overall focus in order of importance:
1. Build up your base FAST.
2. Get some Scorpions attacking the first Flood base ASAP.
3. Rescue the first troops, then take over the map with Scorpions.
4. Escape!

My general walkthrough steps:
1. Immediately build two supply pads and a Reactor.
2. Send one of your Marines to the Reactor that's right behind the Tractor Beam to the right of your base.
3. Get some Turrets up at the front of your base, with Anti-Air on them.
4. Get a Vehicle Depot up, and start training as many Scorpions as possible.
5. Park your Scorpions near the first Flood base, and use them to gradually knock out the Flood flying units. If a Scorpion gets badly hurt, pull it back towards your base, and when enough are hurt, use the Leader Heal Power!
6. If necessary, send your Hornets to the Alpha troops and/or use the Leader Heal Power on them to keep them alive long enough for your Scorpions to break through.
7. Get a Field Armory up(you should have 4 Supply Pads, a Field Armory, a Reactor, and a Vehicle Depot on your base).
8. Upgrade the Reactor, and research the Canister for the Scorpions as soon as you can.
9. If you haven't taken out the first Flood base by now, 5+ Scorpions should be enough, although using a Cryo Bomb on the flying Flood right before you attack is a good idea. Focus on the 'Gob throwing' Flood Towers, and wipe out that area. Possibly run through to Alpha with Scorpions if you need to to defend Alpha, then work from Alpha backwards.
10. Once you've rescued Alpha, you're doing well.
11. Keep building Scorpions, station them at the first flood spawn point so no flood respawns, and heal them up for the assault on the center.
12. Around this time, you should explore North of where Alpha team was, and the far East(right) side of the map for more Tractor Beams. Gremlins will be called in, and send them to those locations for some extra time. (You could even try to explore the last location which is just to the left of Charlie Team, and send a Gremlin there. It may or may not make it)
13. Mass tanks with Canistor shot into the center after a Cryo Bomb, and wipe out the center. Don't forget to leave a few troops behind on the left Flood base so it doesn't respawn!
14. Heal up, take out the little Flood base just North-east of the center base, make sure you're at max population, then take out the final Flood base, as always with a Cryo Bomb first.
15. Once you rescue Charlie Team, the Flood will spam attacks--send some Scorpions near the Reactor you have Marines in, and park the rest in the center of the map possibly--or try to make sure the Flood don't rebuild any of their bases, because if they do the attacks are ridiculous!
16. Send Charlie team the safe path(assuming you took out the Flood Gob Throwers near the North Pylon) along the top of the map, down the left side back to your base.
17. Victory!
