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.
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 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.

It's alright. I understand this guide isn't very clear due to the lack of images placed correctly. Hope you have fun finally with 100% on this game.

Restart the game if sv_cheats has been used in the current session

You're not meant to use sv_cheats at all. These ent_fire commands work in every singleplayer Source game. Be sure to look at the elevator (not standing inside of it) and use the command in console " ent_fire !picker resetplayerstats " without the quotations. Be sure to use the command while looking at the entrance of the elevator but not standing inside it.

Every single time I've tried this, it worked. Please make sure that you're following every step as said in the guide. The images might help however they might be too small a size. Make sure you're not typing with the " " marks and copy everything inside them to the console.

Again, don't know how to and sorry if the image quality is low. Hopefully the tutorial helped anyway (I hope)

The images are quite small, and you should embed the images
