As you may have already guessed this is based off of the movie Battle: Los Angeles. There are 12 achievements and all of them are obtained offline during the campaign. I play the game on Hard during my first playthrough but you may want to do Normal first. I thought the achievements would stack but I quickly found out they didn't. If you play on Normal at first then you can become familiar with the levels which will make Hard even easier.
The game isn't difficult at all especially if you follow a little trick that Dooney found. Go to the settings and turn auto aim on. This is the best auto aim feature I have ever seen. While using the sniper rifle, all you have to do is look in the general vicinity of an alien and then hold the left trigger and you will zoom in center mass. Now pull the right trigger and alien dies. Move on to the next victim. You can do this with any of the weapons but the sniper rifle is one shot one kill.
ACHIEVEMENT GUIDE
Private - 15 points
Complete the game on Easy Difficulty
See Sergeant Major
Staff Sergeant - 25 points
Complete the game on Normal Difficulty
See Sergeant Major
Sergeant Major - 50 points
Complete the game on Hard Difficulty
First off turn the auto aim feature on. Then play the game on Normal so that you can become familiar with the levels which will make Hard easy. Then use the sniper rifle whenever you have it so you can kill the invading aliens with one shot.
Pool and Dive - 5 points
Survive the pool attack
This is campaign related and cannot be missed. If you are having problems then use this tactic: There are two aliens; one jumping out of the pool and one on the roof to the right. As soon as the alien jumps out of the pool, move to the right so that the one on top of the right building cannot shoot you. After you show the pool alien who's his daddy, then teach the same lesson to the one on the roof.
Kaboom - 5 points
Destroy the gas station
This is campaign related and cannot be missed. With auto aim on this will not be a problem, however I did have a small problem here. Once I was told to shoot the truck and that is what I did. I put almost 30 rounds into that dang thing and nothing happened. After a couple of choice words left my mouth I then noticed the gas tank was highlighted and was blinking. The developers probably made it an easy-to see-target so that a dumb - censored - like me could see it easier. I then put one round in it and guess what happened? It blew up and I got the chievo. An epic fail on my part.
Droppin Bombs - 5 points
Call in the airstrike to defeat the Command Center
This is campaign related and cannot be missed. With auto aim on this will not be a problem.
One Hundo - 50 points
Unlock all the unlockables
This will unlock after you beat the game on all difficulties. Should be the last achievement you obtain.
Color Me Impressed - 10 points
Complete a mission on Normal without dying, failing, restarting, or continuing campaign
As long as auto aim is on this shouldn't be a problem.
Long Range - 10 points
Kill 20 enemies with a sniper rifle
You should obtain this by the end of the first level. Most likely will be your first achievement. As long as auto aim is on this shouldn't be a problem.
Hummer - 10 points
Kill 15 enemies on the HMV turret
You have two chances to obtain this; on the second and last missions. However, there shouldn't be a reason you don't get this on the second mission. The auto aim feature also works while you are on the turret.
Rocketman - 10 points
Kill 2 aliens with one Rocket
Towards the end of the second mission you will acquire a rocket launcher on an overpass. After you move on the roof and take out the alien ship you will make your way down a ladder and off the roof. You will then encounter a pair of aliens and after those have been taken out two more will appear. Both of those will be on two separate roofs. After those have met their alien maker you will make your way down an alley to the left. Two more aliens will appear; one from the left and one from the right. If you aim correctly you will be able to take them both out.
Seen Your Video - 5 points
Watch an unlocked video
I don't know if you can watch a video before you complete the game on any difficulty. I beat the game on hard and then from the main menu I went to unlockables and then to videos. Just play one video and as soon as the achievement pops back out to the main menu.
