Manual saving doesn't work, so this depends solely on your skill. If you make a mistake you have to restart the entire mission. Check the achievement guide for details on all of these collectibles. You should collect the Diaries/Jelly Containers/Trophy Belts as well as the second collectible for the Alien: Civilians who must be harvested. You need this knowledge to survive Nightmare difficulty since there are NO checkpoints. This way you'll learn how to play the three species and get to know the different levels. I recommend starting on Hard if you have some skill in first-person shooters. Take note of those two achievements in the guide and make sure you don't miss them. The first is helping van Zandt via killing him before the Alien Larva bursts through his chest and the second is killing all Marines in the 2nd Alien Mission - Refinery. However, there are two story-related achievements that are missable if you don't pay attention.

You can expect some good action, getting the full 1000 is going to be a piece of work.įour of the missable achievements are the collectibles covered in the guide. Welcome to a great sequel in the Aliens vs Predator series.
