Here’s the First Trailer for Left 4 PayDead

Left 4 Dead is a four-person co-op FPS about surviving a zombie outbreak made by Valve. Payday is a four-person co-op FPS about robbing things made by Overkill. The two similar games are going to get a lot more similar in Payday: No Mercy, which is also a Left 4 Dead prequel set in L4D’s Mercy Hospital. Destructoid says the heist involves getting a certain patient’s blood, which you can easily see going bad, especially during the chaos of a hospital-wide firefight. Silly criminals. If all you wanted was zombie blood, all you needed to do was sit back, grab a cold beer, and wait. The zombie blood will inevitably come to you. Thanks to SlyDante for the tip.
