In the videogame Portal 2, the co-op campaign is one of the best around (to find out my thoughts on the game, read my review here).
But, with any co-op campaign, you run the risk of being paired with an inexperienced partner, which can result in a lot of frustration. Or, even worse, you can end up with a partner who knows what they are doing and just wants to mess you up.
So, how can you avoid being that particular player that everyone hates to be paired with?
Thankfully, the lovely folks at IGN have made a video with five simple things that you should never, ever do in Portal 2. If you follow the simple steps, you can rest assured that you will not be a total douche.
Now if only the person you were playing with would watch it, right?
