Valve will be cutting the price of Left 4 Dead on Steam by 40 per cent this weekend to just GBP 16.19. The offer ends on Monday.
To get a taste of the frantic co-operative action, Valve is offering a free Left 4 Dead trial to everybody today. All participants need to do is download the client from Steam, steady themselves and then wade in. That offer ends at midnight.

Creep over to our Left 4 Dead review to find out why.
