Nice guide, I read most of it, really in depth and it's pretty much exactly what I did when I was getting the achievement. Except for the rockets after like set 3. I found them a hassle to carry around, even against the brute chieftains, I'd rather have plasma pistol/magnum combo. During the higher waves, I am rarely able to kill a brute without using all of my rockets even when they're direct hits. You want to save the ammo and use it as little as possible for when you have it, but that way you're also limited which is what I really dislike about it. Good for the first 2 sets, and maybe for when the grunts and jackals start massing in the last 3, but other than that.. I found no other use for it. Oh, and there's a few things that I noticed that I thought you could change, or should add. -change the fire bomb grenades from being dropped by brutes to only being dropped by brute stalkers since they're different from normal brutes and rarely show up. -Brute chieftains can also use spike grenades. -Another good thing about ONI alpha site is that there are no engineers. -Gravity hammers are good when the black eye skull is on because it'll do splash damage, and even though it doesn't seem like you actually hit anybody, you'll get your shields back. -Did you write about during the waves where all the skulls are on except for iron, you should have a plasma pistol and magnum/carbine combo? 1 plasma shot for the brutes' shields, the other with the magnum for the head shot. This is much faster and is more efficient than combining your fire against one brute, as you and your team will burn your ammo very quickly.
I consider any Brutes lesser than Chieftains in one complete category. Heck, I even throw Chieftains in with the Brutes too. But I don't feel I need to extend the Brutes category any further. Stalkers don't cause too many problems. Once again, Brutes use spike 'nades. I got that down. I added the list of enemies to show what is on the map. Anything that isn't there, won't show up. Besides, engineers aren't a real problem. Plasma pistol and you're on your way. Yes, Gravity Hammer does return your shields when you melee, but other people could be trying to melee the same target and wuhblam, you've got yourself a teamkill. I pretty much don't see a good reason to even hold a Gammer while in firefight. I do believe in there I said two people should have PP and P, one explosives and pistol, last member can switch out for whichever problem that arises.
A very well written guide, my friend. Someone sticky this... One more thing you can add is that the Carbine is the most effective weapon against the drones.
Thank you. I mentioned that Carbine is effective against them. Somewhere in the strategies and where I talk about the weapons.
You can also use the hammers to push crates into the stairways, slowing down the flow of enemies, and sometimes even getting them to just stand by the crate and be unresponsive, making for easy targets. But I emphasize juggernaut's warning about the hammer. I was on my way back from picking up a new set of rockets, when someone shockwave'd me with the hammer. I fell into the pit, and we had very heavy casualties in the chieftain wave.
I'm adding all enemies to this guide for a reference to firefight enemies in general. It'll be updated soon.
If you jump when the Chieften with the gravity hammer strikes, you get knocked into the air with ALOT less damage.
Alright, I added a complete list of enemies including all enemy vehicles and more elaboration on some of the enemies, including the Engineers.
