Pretty neat, makes me interested in the real game.
AHHHHHHHH I need help on the 6 level!
level six god doesnt anybody understand that they just have to use a fucking cluster bomb.
im stuck on lvl 23
1. It’s not a mod for Half-Life 2. Just because it uses the same engine doesn’t mean it’s a mod of that game. (Example: Gears of War and UT3 use the same engine.)
2. It’s funny cuz this game is harder than the real game.
3. The real game is better(duh) mainly cuz of the voice acting! ^_^
How the hell do you do level 6?
for level 6
-first open a blue portal on the closest bullseye(red circle thing)
-second open a yellow portal above the paltform in the middle
-third hop through
-fourth jump down into the blue portal but shoot the other bullseye with a yellow portal on the way down
- if u did it right you will get a big boost into the air and be able to move over ont the top right ledge
That worked. Thank you.. any help on level 9? hehe
i quit on that stupid level with the part where u have to teleport onto the platform from the right, shoot straight up through a little pipe, and them jump back through the way you came in about 1 second. fuck that.
nm, i beat it..
I can’t get enough of games like these.
best i got is 37 now
This is gay!
how do you do level 9?
for level 9
- first shoot a blue portal right below the box that says 9
-second shoot a yellow portal straight up
You should be looping now
- while falling into the blue portal shoot a yellow portal to the right of you
if you time it right u should get a boost and fly up to the next platform
-while ontop of the first platform clear portals and jump down
- while falling quickly shoot a blue portal below you and a yellow one to your right (you may be able to shoot the yellow portal from atop the platform making the drop easier)
-youll fly up onto the second platform and you know what to do from there
dang 6 is hard im stuck
this sucks lev. 9 is hard
Yeah beat it. it took a little bit but once you figure out the concepts its pretty easy. little hint you can lift the guns to.

Downloaded the flash file, beat it, much fun. The Orange Box Portal is fun but gets really damn freaky which is awesome. The only problem is it’s too short, took me 2 days. I actually only bought the Orange Box for Portal then got into Half-Life, never played it before, interesting game.

This game is hardcore. I like to caress myself with natural yoghurts when I play this game. I also like to “position” myself in awkward ways. Yumm RANDY..=P
Wow, this gets really hard.
Wow, this game gets hard.
