Portal 2 was meant to have some DLC coming out over the summer, but anyone that knows Valve at all will realise they always take forever to do stuff, despite that I'm not going to mention a certain Freeman at all in relation to this matter. Anyway we know have an actual date for Portal 2s DLC update, which will be free for everyone. No matter which platform you have you will be able to get this no matter how skint you may or may not be. It's good to see Valve are sticking to their roots and still updating their games free of charge, which is why we all love you, instead of going along with what is seemingly becoming the norm in over priced map packs in the form of downloadable content. But I won't get into a rant about dlc because frankly it will take to long and I really can't be arsed with it to be honest.
Anyway getting to the point of this post, Portals 2 update will be available from the 4th of October and will be named Peer Review. It will have both single and multi player challenge modes. Valve have stated "You and a friend will continue the story of loyal bots P-Body and Atlas as you puzzle your way through a mysterious new co-op test track and once again match wits with GLaDOS.", Which means more co-op campaign missions. This shall be getting marked on the calender and I will be playing the new content as soon as possible.
