Then, load a Marine mission on the Normal difficulty with a lot of enemies, such as the Praetorian boss in the "Research Lab" mission. Simply kill enemies now to get easy XP. Repeat this as many times as desired. Finding collectibles: --------------------- While playing as an Alien or Predator, activate your Focus to get collectibles to appear as flashes on the HUD. Avoiding instant kills as the Marine: ------------------------------------- In Multiplayer mode, keep your back against walls to prevent getting killed instantly by Aliens and Predators. Getting past ventilation shaft as the Alien: -------------------------------------------- In Level 3 as the Alien, the Queen will tell you to get to the bottom of a shaft with a huge fan at the top. When you get close to it, another Xenomorph will be blown into the fan. If you use your Focus, you can see two vents on the opposite wall. You can use either of them and safely jump to it despite the power of the fan. As you continue, you will find more vents to hide in. Use them to make your way down.
