Challenge tasks ACHIEVEMENTS using cheats to make easy
By TryHardGamer
Cheat for achievement challenge tasks using only console
This is a way to get the Portal challenge achievements with a cheat but here's the twist, it doesn't disable achievements!
This method uses the ent_fire command in console. If you do not know how to get the developer console then please look in the comments or search how to.
  • The developer console enabled
  • Basic knowledge of the maps
  • Knowing how to solve the level at any pace
Step 1: The playthrough
To start all you have to do is play the map normally and don't worry about your score as that will be reset.

For this I will play Testchamber 13

Playing the map normally, you can see how my step counter goes up to very high levels.

Step 2: The Code
Head towards the exit elevator but don't go in it. Step through the particle field though.
Open the developer console with the tilde key
` ¬
Type this code in

"ent_fire !picker resetplayerstats"

You must be facing the elevator and be past the particle field
Step 3: Success
You've completed it. Just walk into the elevator and soon you'll have all gold challenge medals allowing for 100% completion of the game.

(Notice: I've tried this on all challenges and it works perfectly for my 100% achievements. Please check the comments for questions as they likely have already been asked.)
Extra infomation
If your achievements in-game are not up to date to steam then delete the gamestate.txt file in your Portal directory.

Literally everything here proves that it works. Complete the course. Go past the fizzler. Look at the elevator but don't go inside. Open console and type exactly what's on the guide.

The comments and evidence from my own profile doubts that. Test it for yourself, this is legit.
