Somewhat easy to do, Just avoid enemies when you can and make good use to vehicles. Its best to drop the SMG and replace it with a better weapon, The SMG takes way too many bullets to take an enemie down.

I'm at the part where you have to protect the engineer on the highway with a warthog on the last section where there are a bunch of ghosts and banshees with low health. I made a mistake of giving Buck a rocket launcher so now he won't use the turrets on the warthogs and he shoots rockets in the air. Is it possible for me to load my game and have someone join me or will the level have to be started over?

The lasat level protecting the Engineer should be much easier if done Co-Op, everything else just takes time. If you can jack a Ghost or unlock a garage with a Mongoose you can just ride quickly through the streets from location to location as the Rookie thus skipping many battles.

I finished it yesterday, but for some reason it was bugged for me.
I had to replay ONI Alpha Site and Coastal Highway (annoying)
I was playing a local co-op with second controller on idle for spawning (lame, I know, but it gets you there).
When I got to Dark Hive I noticed that I don't have the ONI Alpha Site achievement, then I didn't get one for Coastal Highway, nor any of the Complete Achievements. So I have replayed theses levels and boom, they popped :).
P.S. I noticed some threads where people where complaining about those 2 levels on online co-op.

ok for those of you not afraid to do this SOLO, here is a tip. beat the game on normal or easy first unlocking all the audiofiles, as these unlock AWESOME weapons caches which have rocket launchers and sniper rifles and mongooses and LOTS of that awesome pistol ammo. then choose REPLAY from the campaign menu on legendary. of course this doesnt help with the actual flashback missions, however keep in mind your ODST brethren are TRULY immortal and can help immensely in those tough firefights. i have watched the other odst get completely pink with needles and several stickies AND wraith blasts all a once and he still keeps rockin.

I don't have a mic and because of that I don't join parties. After all it will just be us alone so game chats fine ._.;
Also, if you want just one that's on the list, send me a message. I'll still help out. I'm also willing to help people do the campaign on legendary.

Just finished this on Legendary Solo. Toughest part was the HIGHWAY (last) level, when you're escorting the Engineer. The part I replayed many times (which means I DIED or failed) was after Buck says to switch to the Gauss Warthog. Other than that, the very last part I replayed once (damn Brute with the Gravity Hammer).

Overall, the game was a bit tough, but definitely doable solo. Use lots of cover, have ranged weapons (Carbines and Rifles), and pick them off one-by-one.

About to take this on Solo.
I recommend using (or at least checking out) Mythic Tyrant's Legendary walkthrough on YT.

Also, as previously stated, play through the Campaign on Easy first and get the Good Samaritan & AudioPhile achievements. This way all you're concerned with is killing/evading. Plus you unlock the Weapons/Supply Caches by getting all the Audio Logs.
When possible, give your ODST squadmates power weapons. They will have Infinite Ammo and they are invincible. (They seem to LOVE killing covenant, as opposed to Halo Reach where your fellow Spartans want you to do everything.)
