Well, Valve never really announce that they will be working or releasing the third sequel to the popular game Left 4 Dead but the people seems to believe that it is happening. Here is what we have so far.
It is believed that Left 4 Dead 3 will still be a 4 player game and this time the 4 characters will be Irwin, a hoodlum, Katherine, a former stewardess, Garret Jr as well as Keenan.
The game will have 6 campaign from the start including Inquisitor Land, Early Destination, Cliffhanger, Crash-Land, No Mercy, and Impasse. The fact that it has a No Mercy campaign had us thinking if this is where the new character might stumble across the characters from the first Left 4 Dead game. We did see them make a short appearance in the second game so why not? Are we overthinking it?
It is said that after a long break, Valve will finally be announcing the game at E3 this year. We do not know if any of these is true so all we can now is wait and see.
