This mod does what it advertises: slow zombies in left 4 dead 2.
It's a different take on the l4d2 gameplay. Even though the zombies are slow, they will incapacitate survivors with one hit. This is, in my opinion, needed since you can outrun zombies very easily.
It has its flaws but this is the best mod of its kind. I have tried all others that are publicly available, and this one comes out on top.
i highly recommend playing this with Human Survivors. The standard NPC survivors are not programmed for this mod.
Custom weapons are a very nice addition, but the Custom snipers' scope isn't aligned properly. Avoid custom snipers and take only the Hunting Rifle.
Melees are hidden from the menu, for some reason. You can use melee if you press your main weapon slot's number key again on your keyboard.
Some melees are vastly superior to others. I highly recommend taking the crowbar or the fire axe.
The headshot hit register isn't always accurate. But this is l4d2's fault, not the mod's.
Some maps are better for this mod than others. I'll leave it to your discretion.
All the people complaining are provoking their own problems. Why would you install a "slow zombie mode" if you don't want slow zombies in your game?
The best of its kind
