This is a very good collection if you want to make the best of it when you want to play the MP_Beach map from RTCW: ET or any other world war related maps,
in this collection you'll find mods for survivors, common & special infecteds, weapons, items, objects, sounds, ...

If you get a crash during the game with all these mods, disable the shotgun mods, when i tried to pickup a shotgun then my game crashed every time.

When you will use the survivor skins from this collection together with these weapon mods, then you'll notice a visual glitch which kinda makes your arms stretch out in the game, to solve this you have to let a special infected grab you so the camera changes, when the camera moves back to first person from then then the visual glitch will be solved and you'll be able to use all weapons without experiencing this glitch.

If by any chance you have a VR headset, then i strongly recommend that you try this mod combined with the VR mod for L4D2 which you can find here: https://github.com/sd805/l4d2vr

IMPORTANT
Do you encounter this error?: 'Server is enforcing consistency for this file'
After you get this error, open the console and enter sv_consistency 0 ( It might be sv_consistency = 0 (But you can do both in seperate lines)
I managed to solve the error issue by entering that line in the console AFTER i encountered the error.

Have fun!
