Left 4 Dead is one of the most popular shooters released last year, despite being a brand new Intellectual Property. It won over a lot of fans thanks to its solid multiplayer features and the great matchmaking system guaranteed by Valve's Steam service.

Even though it experienced a lot of big sales in the holiday season, the game has also seen various surges thanks to different types of promotions Valve has endorsed the product with. Now, with the brand new Survival pack free DLC, the video game has once again become very popular.

But just when a lot of analysts believed that Valve couldn't do anything more extreme to promote this title, the company has just announced that, beginning this Friday, at precisely 12:01 AM GMT, the PC version of the game will be completely free to play. That's right, for 24 hours you will be experiencing one of the best online shooters completely for free, with no obligations.

“Beginning Friday at 12:01 am GMT, the PC version of Left 4 Dead will be available for a free 24-hour trial via Steam” reads the announcement made on Steam. “The free trial will include access to the recently released Survival Pack DLC, which introduces a new multiplayer game mode and two additional Versus campaigns. Those who wish to give L4D and the Survival Pack a try may now pre-load everything needed to play with no obligation to purchase.”

In case you were still on the fence about whether you should buy this great game or not, then this deal will certainly make you decide. Left 4 Dead has a lot of interesting features, coupled with exciting multiplayer modes, and, now, the price just can't be beat. You'd better start pre-loading your game and get ready to shoot a lot of zombies this Friday.
