Battle: Los Angeles

Due to this game not stacking the achievements that means for this achievement you'll need to complete the game on the normal difficulty.

The game isn't very long and shouldn't take you much longer than an hour to complete, it comprises of 3 levels none of which are overly long or tough. Rather then create a text based walkthrough for you to follow I've put some videos below for you to follow. You can use them to learn the level layouts and enemy spawn locations!

It's up to you how you choose to play, I'd suggest to hang back a little and use the sniper rifle to pick the enemies off. If you have a good aim you should be able to kill most the enemies with a single shot when aiming for the head or chest. Lastly, instead of holding the sprint button it's more efficient to tap it in short bursts and it'll make it last longer.

Complete the game on Normal Difficulty. The difficulty achievements do NOT stack. So you must play through each difficulty once.

Tips

-Do NOT rush towards the enemies. Stay far back and behind cover. Use crouch to stay low behind cover and pop out when you are not injured to shoot enemies.

-Avoid hiding behind cars because they can blow up. If you need to hide behind a car, make sure it is not on fire.

-Try to go for head shots or torso shots

-When you are injured, hide behind cover until you are fully healed. To be on the safe side, hide behind cover BEFORE your screen goes black and white with read around the screen. This means that you are near death.

-When fighting the Alien Air Units with the Rocket Launcher, there is a good strategy to kill them faster. Right as they start charging their shot, shoot your rocket launcher at them. Reload and shoot again quickly as possible. You can sometimes get 2 shots off before waiting for them to charge again which makes the process go by twice as fast

-You can make the game even easier by turning Aim Assist "On". Go to Help & Options, then Settings, then Game Settings to turn on Aim Assist. Make sure you click to accept. This will make sniping much easier too. An effective way to cover Nants when ever you need to.
