If you do not own Left4Dead2 (or at least the 1st one), then I have no words...

I would suggest you buy the game, but if you don't intend to, then it might be best to leave the group to avoid getting spammed my random "Let's play" announcements.

When we announce the random "event" we will also include TeamSpeak details. Make sure you read the details.

Looking forward to some crazy random fun with as many people as possible.

Best regards,
Aka
