Valve is offering you the chance to get your mitts on the awesome zombie co-op shooter, Left 4 Dea, for free. And we know you like 'free'.
Valve sent this note over: "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."
If you don't have it yet, this is what you're missing:
"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."
Don't thank us, thank Valve. Hit up Steam and get pre-loading.
