Left 4 Dead: Haunted
What: Mod
Who: The Group Thing
L4D: Higher than average mob numbers, multiple spawns of specials and a generally harder trek through the maps. The mod is designed to make the game unpredictable and we think it does that quite well.
L4D2: Our L4D2 Haunted Servers are running the new Haunted 2.0, which has been adjusted to make the Haunted L4D2 experience smoother. You can expect the common zombies to be tougher, mobs to be larger, multiple specials to spawn and of course the general air of unpredictability that accompanies the Haunted mod.
