Multiplayer Achievement Help

Use hax xD

Sadly I don't know of anyone who didn't play the game online, sorry

Easy (?) way for Professor Portal. Search for random people until you see the opening cinematic and play the "tutorial" course - it only happens if you are playing with someone who never went co-op. Talk with that person, add him/her to friend list and restart co-op. Be sure NOT to complete that tutorial stage unless you have that person added as friends. Cheers!

I didn't play it online yet, but I still have to beat the first one.

Need help on L4D2 Strength in Numbers and Chaos Generator

Good idea. But there is so many games and many MP achievement.
Anyway, i hope tomorrow i'll fix my PC, so we can play together (i didn't play Portal2 yet)

Dont have Portal 2, but if someone wants to complete an achievement for an MP game and i happen to have it, go ahead and let me know.

Hey ! I've got portal 2 and havn't played it online yet, if you still need it just add me!

Any other games you need help with?

I still didn't played also the single player, so let me know if I can help you :)

I'm still missing the achievement in MTG: Duels of the Planeswalkers (the 2010 game, not 2012) for winning a game with 3 or 4 players. I could also help others who need online achievements in that one or in 2012.
