Every gun is spread throughout the game and can be found almost very easily, but you could be missing one or two cause you ran over them and didn't look. You first find your Predator Heavy Pistol in the locker at the beginning of the game, later in that same mission you come to an lift and beside it is the grenade launcher. After you complete this mission you get the Avenger Assault Rifle, Katana Combat Shotgun, Mantis Sniper Rifle, or the Shurikan SMG in the opening of the next mission. Later on in the game you can get Vindicator Battle Rifle, which is located in the mission you go to get Archangel (a.k.a. Garrus) when you meet him there is a bench in the room he is in it is sitting on it. Next the Canifex Hand Cannon is found in the mission you go to find Mordin, when you meet Mordin in his clinic he hands you the Hand Cannon. The Viper Sniper Rifle can be found all throughout the mission you go to find Thane the Assassin, next to a terminal where Nassana is talking, next to the bridge you take to switch towers, and on a u-turn next to an elevator which brings down a mini-boss. The Schimitar Assault Shotgun is found in the mission you go to get Samara, it is found on a desk on the right hand side of the room near a weapons locker, sorry don't remember fight that occurred right before this. Next you find the Tempest SMG in the mission you go to find Tali, it located next to a dead Geth Hunter, some Geth Troopers, some Quarian soldiers, and a radio where you communicate to a Quarian captain, I don't remember his name sorry. Also the Geth Pulse Rifle is found in the same mission you go after Tali, it is found at the end after you fight the Geth Colossus and before you talk to Tali, there is a large Geth dead on the floor through the door and on him is the Pulse Rifle. Almost every heavy weapon is a Tech Lab Prototype, but the flamethrower (not including grenade launcher cause you have to pick it up) is found in Zaeed's loyalty mission you must have the Cerberus Network to get this, it is on the floor after you have entered Vido's base after you are finish talking with the civilian who says they are trapped. The Locust SMG is also found in a downloadable content with Stolen Memory, Kasumi's loyalty mission once you get to the Graybox sitting next to it is the Kassa Locust. Then the Revenant Machine Gun, Claymore Heavy Shotgun, and Widow Anti-Material Rifle are all found in the Collector Ship once you finish the scene when you find out the Collectors were once Protheans you automatically have to pick one up.
Here's a very easy way to take down husks. What you have to do is use your heavy pistol and equip it with the cryo ammo ability. One shot then it freezes and blow up. When your up against a lot of husks like when your on the derelict reaper to aquire its iff it really comes in handy.
When you gain the loyalty of both Jack and Miranda they will have a fight. Tell Miranda to back off (this will cause her to not be loyal). At the suicide mission don't put Miranda on any of your teams. This trick will only work for people who don't have enough Paragon or Renagade points.
Fighting on Insanity seems easy for the first mission, because its like every other difficutly, but when you reach the first mission that you get guns other than the Predator Heavy Pistol and the Grenade Launcher, things get tricky. Enemies now have ridiculous amounts of health, standard mechs no longer just have health they have a layer of amour too. Things are a little bit harder there, and they eliminate your sheilds in two to three bursts of their Shurikens. Also the dog mechs get armour as well. This mission you start out with a shotgun, assault rifle, sniper rifle, and/or sub-machine gun (or the one you do when right after you meet the Illusive Man, but before you meet Joker) is the hardest mission in the game, because you have no upgrades and the worst guns in the game for this difficulty. Once you pass this mission the game gets easier, I promise, mainly if you imported this character so you have more guns once you get on the Normandy SR2. Personnally for this difficulty I would suggest using the Soldier Class too, two main reasons: five weapons you hold at once and ADRENALINE RUSH! Use Adrenaline Rush like crazy get this evolved in your stats, it will save your life! Also if you have the points I would suggest both the Firepower Pack and the Aegis Pack for this game, because the new armor, assault rifle, sniper rifle, shotgun, and pistol are too good to give up. Trust me that name is what it is FIREPOWER! Don't just quit after that second mission the rest of the game is a breeze compared to that. Just remember: Don't ever be the big hero, sit back relax and Adrenaline Rush use it, you'll eliminate your enemies so fast they won't know what happened, also switch your ammo types even if their health is going down, you will have more ammo later, when you'll need it.
You know the part in the game were you board the disabled collector ship? Well about 5 minuets into the mission you come across a dead collector on some kind of dissection table or something like that. After that you walk up to a pile of advanced weapons. If your a soldier class you have 3 advanced weapon choices the claymore shotgun, revanant machine gun, and the M-98 widow sniper rifle. Choose wisely.
You know Samara the asari justicar? Well on her loyalty mission were you have to help her kill morinth the ardat-yakshi, when you get to the part when you and morinth are alone in her apartment, (make sure you have a lot of paragon points) then samara walks in there is a pause in the battle two speech options appear. One says kill morinth the other says kill samara if you choose the kill samara option morinth will take her place.
Want to know a very useful ability? Shredder Ammo. Shredder Ammo is very effective against organic hostiles which are who your shooting at most of the game (except the geth of course). Also when you get up to the point where you can evolve Shredder Ammo I recommend the Squad Shredder Ammo choice because that gives your entire squad Shredder Ammo abilities.
You know the Tactician Achievement? Well here's the easiest way to earn it. Before I tell you what to do the best soldier type to use to unlock the achievement would be an Adebt. OK first get one of the biotic members of your team like Samara, Jacob, Miranda, Jack, or Thane to use the ability Biotic Pull then have your character use Biotic Throw. Do that 20 times and you Unlock the Tactician Achievement.
In order for your squad to survive the suicide mission you should do the following. First, send Legion to open the door to the central chamber (first choice), Second, send Samara to escort Dr. Chacquas back to the Normandy (second choice), Third, have Garus lead the diversion team (third choice). Last but not least have Mordin Solus in your party when you initiate the final step in either destroying or capturing the collector base beyond the Omega 4 relay. Good Hunting.
After the suicide mission talk to tali (quarian) she will talk non-sence just keep saying your interested and stuff like that then go do a mission for loyalty on anyone if you didn't do all of them then go talk to her again and say you only want her then sit back and enjoy the scene.
To resources en masse, you have to scan unexplored planets and launch probes when you find some. To scan you have to enter orbit around the unexplored planet, and hold LT to scan around the planet. When you feel you controller vibrate, hit RT and launch a probe. The more your controller vibrates the more resources you will get.
The first one is crude but it is effective.
Look for spots that don't mesh with the landscape, random craters, oceans, ice caps, belts, ect. This is where most large spikes are.
The second one is more tedious but nets more income.
1. Place the target on the very edge of the planet with out turning it.
2. Start scanning and use both thumb sticks to move the planet and the scanner.
3. Do this to coat the whole planet, yes it takes time.
4. When done in that row, move up or down the diameter of the target.
5. Repeat as needed.
When the Collector in front of you turns into a Harbinger You have signed a real date with death. This is a quick guide to take them down fast. Take Garrus or someone else with concussive shot and anyone else, even two concussive shot guys help. Use these to drop the Biotic Barriers that it puts up, then open up his chest cavity with a load of armor-piercing ammunition. If you have the Widow, use it, one head shot and he's down for the count. Note that it is unadvised to take one of these guys head on. If you are using an infiltrator, use incinerate between sniper shots to maintain ammo. This will weaken its armor, just watch out for his little fire balls too, they hurt more than a level 4 fire ball.
