Overrun Mutation Pack

"Overrun", another singleplayer mutation mod that aims to bring the survival experience to Left 4 Dead. "All Alone" veterans will be particularly pleased with the challenge this gamemode poses.
Mastered the art of sneaking around zombies with melee weapons?
Can pull off headshots without looking?
Put it all to the test in "Overrun", a mod that employs the same set of skills as "All Alone" in a very different way.
List of gameplay effects:
-No teammates (AI or human). This is a solo mutation, like Last Man on Earth.
-Ammunition is doubled for all weapons except the SMGs
-Zombies have been slowed to the same max speed as the player can go, meaning it's possible (but VERY impractical) to outrun them.
-Most zombies die in one shot (two shots on expert)
-You'll go down in a mere 16 hits on easy, 8 on normal, 4 on advanced and 2 on expert.
-No special infected besides tanks and witches.
-Tanks have lowered health and move just a little slower than a healthy survivor
-No random zombie hordes/mobs; take your time and search around.
-Fallen Survivors are easier to kill and spawn more often on maps where they're available
-Shove cooldown kicks in after one shove
-Adrenaline length doubled
-Some other small details
Now I know what you're thinking:" Fine, this sounds like an easier version of all alone! What's the catch?"
No catch.
Except that maximum zombie spawns have been increased to 100 zombies. Everywhere you go is a zombie party. Look at the screenshots. I killed 700 zombies IN ONE CHAPTER.
The maps are literally overrun with zombies. They're easier to kill and you're better equipped than in "All Alone", but that's all pretty moot when there's twenty gorillion undead per map.
So...
have fun. :^)
Protips:
-Don't rush it. Take your time and be ever alert and careful.
-Choose your secondary carefully. Magnum for carefully picking off the undead, melees for a sneakier approach or akimbo for a guns blazing kill-everything-in-sight run.
-Keep your weapons loaded at all times.
-Avoid open areas, like the streets of No Mercy. That's where they spawn by the truckloads.
-If there's a lot of zombies, try sneaking past them by crouch walking with your flashlight off. You might just avoid a deadly confrontation.
-Always keep a grenade handy.
-Don't rush unless you have adrenaline and your destination is clear.
-Don't rely on your primary. You have an infinite ammo secondary for a reason.
-If all else fails, just run.
Once again, I strongly reccomend LoadedAK's "Selective Fire" mod for ammo conservation and making each shot count. You can DL it here: http://www.l4dmaps.com/details.php?file=22370 or just search for it on the workshop.
Cheers.
Here's the original mutation that this one was based off of: All Alone.

-Permadeath (sent back to lobby when you die)

Co-op mode features:

Enjoy!
