Left4Dead was always going to be great, that much we knew. It was coming from Valve and it was about zombies, so even before it was unveiled as a four player co-op we all knew we were going to be in for a good time.

Yet still, Left4Dead managed to surprise us in a number of ways, for reasons both good and bad. On the one hand we were utterly shocked to see how effective the AI director is at making the game unique and constantly replayable. On the other hand though, we have to admit that the levels we played through did seem a bit on the small side and it’s getting to that point where the Source engine might be starting to show its age. The thing is four years old by now and though continued development and expansion has helped, the cause is starting to flag a little.
