Beat the Challenge - 20
Complete all Tactical Trials
Complete each of the Tactical Trials, the first of which is unlocked after finishing the first level in Tokyo. Below you'll find my general strategies for quickly getting through the levels for the achievement. In most cases you won't be getting a ton of points, but points don't = achievements, do they!? The strategies work up to at least Advanced difficulty, but again, that doesn't matter for achievements either (nor does it impact the gameplay all that much in my opinion).
Trial 1 - You need to destroy 4 generators, each of which is guarded by a different type of tower. The trial is pretty straightforward, and isn't too hard to accomplish using a tank-shield-tank formation with each upgraded accordingly. Be sure to use hit and run tactics on the enemies on the right side of the map so you take mostly shield damage, and do note that the bottom left enemies are scorchers, so don't take them head on.
Trial 2 - Very simple, just make it to the end of the map without blowing up the mines. To do this, make a straight path to the end of the map and put two shields in your squad and upgrade each. You can probably do it with just one but two works no problem. Don't expect a high score using this method, but it's easy :P
Trial 3 - For this one, you have a limited amount of starting cash and you cannot purchase units once you start the trial. Instead, you must pick units up along the way. I started out with a shield and a crawler and went pretty much straight through the map, picking up a Dragon, another shield, and two tanks along the way. You start off with only one of each ability, so you will need a lot of firepower to get through the last portion of map as there are a ton of towers and the forced-direction areas can be tricky. Once you reach the wall of towers, you have to go down, then all the way back up and then all the way back down to the center of the map to avoid getting toasted by either of the scorchers. Overall not too bad once you get a feel for the last minute or two of the trial.
Trial 4 - What may at first seem like a difficult concept, is actually pretty simple. Instead of the orbital laser working like it did in one of the later levels of the campaign, only one laser can be active at a time. That means, as soon as you cross into a red circle, that laser will be activated and you are free to move through the now grayed out circles. The best part about the orbital laser is the fact that it also destroys the towers! That means, the best way to handle this map is to move from generator to generator by first crossing into Tower-occupied red circles and moving out for a period of time while the laser hones in on, and destroys everything in the circle, clearing the way for you. Properly moving in and out of the lasers to have them do all of the dirty work for you will leave little room for error and death brought on by the towers, making this a pretty simple trial as long as you have at least one vehicle that can attack (I went with my usual tank-shield-tank setup).
Trial 5 - In this scenario, you need to make it across the map without the luxury of gaining abilities for defeating towers. So what does that mean? Start off with shield-shield-APC and go straight through the map, and above the scorcher at the far end. While the map is just starting off, move your commander all the way right on the map to the scorcher that is facing way you're coming from and use both air strikes on it to get it out of the way. Once your convoy reaches the Carusaurum, add either a couple of tanks or a couple of shields to the front of you convoy and at least one of you group should make it to the exit just fine.
Trial 6 - In this trial, you must escort a dinky little APC across the map with a preset convoy and you will not be able to buy or sell units for the duration of the trial. Luckily, there are a ton of caches at the beginning of the map. Basically, to get through this map I would recommend starting off by upgrading one of your crawlers and upgrade the supply truck twice (you need a single decoy, and then upgrade to bomb to bomb the super scorcher at the end) and move through the streets on the far right of the map to collect all of the caches. Keep the dragon at the front of the convoy for this portion. Once you have collected all of the caches, feel free to upgrade the supply truck twice so it will start making decoys, and put your crawlers at the front of the convoy (both upgraded twice), to spearhead the charge against the row of bomb towers, make sure you use your commander to distract all towers as much as possible (Your two crawlers need to die before they make it passed the two regular towers at the end of the road). Once you're through there, adjust your path so you loop around the road just after the row of bomb towers, allowing you to take your commander left to drop all of your air strikes on the landmine, which will detonate the towers and probably give you a new decoy. Continue onward, and be sure to go up and take out the row of regular towers, with your dragon at the front of the convoy (All of your remaining attack vehicles need to die here. Using a Dragon upgraded once and healing it once, just after it passes the first tower will usually accomplish that for you). Once you reach the area with the two stormrays (lightning towers), use your commander to face them away from your convoy and just as the convoy moves in range, use a decoy and a smoke screen to keep the towers busy. Repeat that one more time and your convoy will make it safely to the other side. By the time you reach the final stretch you should have one smoke screen left, which you will use to pass the super scorcher and finish up the trial.
Mayhem Rearmed - 20
Complete Baghdad Mayhem Rearmed
This mode is unlocked upon completion of the game and can be found under Baghdad Mayhem in the main menu screen. It's basically the same deal as the regular version, with 8 additional waves, thus introducing all of the enemy towers.
As far as a strategy goes, following my basic guidelines for the regular Baghdad Mayhem for the first 10 waves is a good idea, after that I recommend switching at least one of the two tanks to a Dragon and upgrade that. Also, now that the last few waves have the towers that repair dead towers (Energizers), make sure you run ahead of your convoy and use an air strike on those towers to make your life much easier.
With Style -10
Use 4 different abilities simultaneously
You will unlock your 4th ability, the air strike, in mission 8. Once you have received that, simply wait until you have at least 1 of each ability and then use them all at once via the + in each direction. The easiest way to get the achievement done is to just pop all 4 abilities in sequence one right after the other; Smoke > Decoy > Repair > Air Strike in that order, running around between each of them to actually utilize them may take too much time since all 4 need to be up at the same time.
This Stuff is Good - 10
Collect 14 Carusaurum caches
You will start seeing Carusaurum caches on level 3 - Carusaurum, which you can actually get this achievement on too. The caches are distinctly marked on your tactical screen as glowing triangular objects scattered across the map. Simply set a path that brings your units (since you "collect" the caches by having your vehicles shoot them) by 14+ of these caches and you're golden. Carusaurum = money so if you don't get 14 caches ever, you're doing it wrong.
