i'm loving this as someone who played over 95 hours of left 4 dead 2 on steam i just have a couple things to complain about.

1. The adrenaline shot doesn't do anything.
2. Only way to get more ammo for the m60 is to drop it and pick it up again.
3. Not really a complaint are you planning on adding the counter strike weapons from the German version?

Other than these been nice job.

Thanks for the feedback, i'll answer some of these questi

1 - There is an issue on gzdoom that makes the adrenaline shot don't work properly. I've currently not found a way to fix it, so this particular item will work best on zandronum. (On zandronum, it increases your max hp by 10, so the more you inject, the more max health you will have. At least until you reach a max amount. Can't remember the number as of now.)

2 - Technically speaking, that's a bug that haven't found a way to solve. You shouldn't be supposed to get any ammo from that weapon at all until you pick up again that weapon somewhere else. Since the M60 is a special type of weapon, just like the chainsaw, it is meant to have some limited use. Only solution I can think of so far would be to make the drop don't spawn the used weapon so it couldn't be picked up continuously.

3 - There are no plans for adding the german version of the weapons.
I'm pretty much done with this mod. I have some minor updates on mind sometime on the future, but there won't be new weapons, maybe some sprite fixes and code improvements. I'm currently too busy with some other mod's (blorc, titan, q4 rip vol 5, csdmo)
I hope this answered some of your questi

Hi there ...any idea why your mod doesn't work with the left 4 dead enemies ?

The mod got updated today.

The mod is still not compatible with the original monsters, but a fork was made for this mod so it won't break the mod while loading these monsters.

Most likely to work on lzdoom and latest versions of gzdoom.

Haha, little does he know I was working on a update by the time he wrote that "feedback" if you can call that a feedback.

Deleted skulltag compatibility in exchange of lzdoom compatibility, fixed some sprites, improved code and the mod is now compatible with left 4 doom monsters via a custom fork made for the mod (lzdoom only)

The mod just got updated. This is the current changelog.

All lowres/highres weapons sprites were tweaked.
Reduced sprite shakiness on all weapons.
Blood no longer spawns underwater.
Low res sprites now merged into staticbase.
Weapon melee now throws enemies away akin to l4d2.
Mod is no longer compatible with Skulltag.
Rewrote some weapon actions, like reload and zoom. Now uses native wrf functions instead of jumpifinventory.
The mod now features custom bob. Sprites are no longer static while moving.
Blocked bob on certain sprites that shows the cropped sprites while bobbing.
Added bob to melee action.
Increased lowres size on some sprites that shows the cropped sprites while bobbing everytime.
Fixed few issues on HUD
Added mod options menu.
Added toggeable crosshair recoil.
Added an optional reduced recoil mode that takes away recoil on stock actions.
Added optional L4D2 monsters, taken from Zdoom forums.
Added alternate death states on vanilla monsters, based on which weapon player uses, akin to "the unmentionable mod".
Added an improved batch file to load the mod.
Deleted the autorun launcher. Although cool, I no longer have the editor to change autorun parameters. Since batch files were renamed and autorun no longer worked.

All you need to load is the L4D2_STATICBASE.PK3 and The L4D2_DOOM.PK3
They are in the base folder in the rar

I'm sorry, but if possible, can you make an L4D mod that is only available for free Doom or for free Doom? I'm asking because I don't have money to buy Doom 1 and Doom 2. I'm sorry if it's a nuisance.

There's a bug were even if the desert eagle is full, it will still play the reload animations if you press reload.

And also, will you update this again and add the actual hands of all the characters and not just ellis's hands for all of them?
