Let's face it, the L4D2 interface has aged a little badly, for those who love the minimal and the elegant and for those who like to have everything in one place, I provide this combination of the two best mods for the game's UI in my opinion.

* Slim HUD offers us dynamic animated healthbars with a pulse indicator that's accelerating while the character loses health, includes the team health counter, in addition to slightly redesigning the weapons panel and repositioning it in the lower right corner. Also modify the interaction bar (appears when we heal us or when we activate a generator) as well as making the damage indicator more visible.

* NeunGUI completely redesigns the game's interface, modifying the appearance of the survival timer, the gas can counter, the statistics of the Survival, Scavenge, Versus modes and the chat box to a transparent black that looks great, among many other things for sure.

These two addons were born to be used together to make the game look better and that's why I am uploading this.
This with my edit of the Eranthis icons is a breath of fresh air to play The Last Stand Update.
I didn't modified anything in terms of design, just replace files to avoid conflict between both addons. Enjoy.

Issue: A transparent black rectangle appears in the upper left corner when you play single player, I don't know why this happens but I don't think it is too annoying.

If the original authors disagree with this they are free to report it.

I'll upload it to the Steam Workshop as soon as I can.
