So you’ve downloaded Portal, played through the incredible story and have decided to get all the achievements. Good for you! Here’s how to do it:
This one is story-related achievement so you’ll get it as you play. You obtain this achievement by acquiring the other colour of portal.
For this one you must put your companion cube into the incinerator. Sad, but you must do what you have to to survive.
To achieve this, you must escape the fire pit, which, when I played through the game I almost didn’t do. Good luck.
You’ll get this once you have defeated GLaDOS and have beaten the game.
This one is quite simple, as all you have to do is pick up a turret and knock over another. They never did anything to you, you monster!
To get this achievement you must wait till after you have both colour portals, which you can’t get before chamber 11.
This is a slightly tricky one as you have to get a very long test chamber and jump 300 feet. One of the best rooms to do this in is the turret ambush room.
After you’ve gotten rid of all the turrets, then place a portal on the wall and then another one on the floor and just keep jumping into it until you have the achievement!
This achievement is quite easy, as all you’ve got to do is detach some security cameras off the wall.
This achievement isn’t available on your first play through of the game so you’ve got to wait to get this one. You have to find the hidden radios, pick them up, and wander around like an idiot for an hour trying to get the light to turn green. Simple.
