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.
Easy "Ain't Got Time To Bleed" achievement
During the first wave in Survivor mode, kill all enemies except one alien. Let the alien get close and hit you once or twice, then run away while your health regenerates. When the alien gets close, face left or right, wait until you get hit with the claw, and then run away. If the alien tries the headbite, try to avoid it because it stuns you for a while. If you let the alien slash you once, it will take away approximately a half bar of health; thus, you will have to let the alien slash you 60 times to regenerate 30 bars of health to get the "Ain't Got Time To Bleed" achievement. It is quicker to let the alien slash you twice, but is not as safe as just letting it slash you once.
Easy "Spin Doctor" achievement
At the checkpoint in the "Ruins" mission where you must activate the three species symbols switches to open the exit, activate your stealth, and bring up your Battle Disc. There will be two soldiers standing by each other. Line up it so you can hit both soldiers with the Battle Disc. Hit both soldiers to get the "Spin Doctor" achievement. If you fail to get the achievement, reload the checkpoint, and try again.
