Well guys, I'm back to making more collections for L4D2, and this one is actually a pretty personal one idea wise. Think PA:II but what if it was more Russian? Inspired by games like S.T.A.L.K.E.R, Metro and a bit of EFT, this collection is based around Nuclear Horror aesthetics. Expect some content to overlap with PAII's 'cause they're the same in theory except one is Resident Evil at home while the other is S.T.A.L.K.E.R. at home.

In terms of game play, this is the hardest collection I've made that isn't built for being hard. The best way I can describe this, is that the difficulty is a mix between PA:II Hardcore and PA:II regular. This is essentially Hardcore Arcade for PA:II.


3 Years after the 2005 nuclear tests in the Yuktonov Valley, the local environment had begun to change. Animal and Man alike began to change and eventually, the area was overrun by the monsters that inhabit it. The Russian Government had created a "safe zone" for survivors in the Valley. In order to get to that safe zone which was located at the border, the survivors in the Valley were forced to move through the "Zone" as they called it. Most who have attempted to do just that have been reported to have been killed by the monsters that inhabit the zone and those who stayed behind were mostly torn apart by whatever was there. Although the monsters were born through the nuke's effects, some survivors have rumored about something in those bombs which suggested that they weren't just your average nukes...

Note: You might need this for some campaigns, who knows?

S.T.A.L.K.E.R. Skyboxes It's neato to have for spookier nights
Any form of Gun Recoil mods if you feel like breaking your back instead of a snail
This specific L4D1 Style Menu I use this one the most and thus will be the example here
S.T.A.L.K.E.R. Style Scope clearer and might give a visual advantage
Apocalypse Color Correction an alternative CC you can use if you want more action focused gameplay


1. All Weapons have a "weight to them", so some are lighter than others
2. The Machine Gun can stagger SI from the sheer strength they have
3. Aiming at the hip with snipers is not recommended
4. Those things they call "Spitters" have a nasty acid that stings like hell and slows you down
5. The fat thing's vomit thing can coat anything, watch your back
6. The horde is reported to attack every 5 minutes, so move fast
7. Your flashlight isn't enough, try hanging with some buddies to keep visibility up
8. The laser sights left behind by the mercenaries can function as a crosshair for your snipers

Simple: "Echoes" refers to the survivors in the valley, "Echoes" represents the survivors' presence in Yuktonov being a bit faint, but their cries of help are still loud as ever. It can also be used to refer to the monsters, with the Echoes representing their general presence and the terror some survivors have when encountering them. While "Abyss" refers to Yuktonov Valley itself being a dark and dangerous place with seemingly no way of escape.

I highly appreciate it if you would show support to this modpack by favoriting it and maybe sharing some feedback. Echoes and all the other mod packs I made were made with a ton of love after all

Special Thanks to my friends for testing this modpack, I really appreciate their support <3
