This is my 3rd mod and the 3rd alternative. If the mutation version is too much of effort to activate it while you also want to use the demonic melee weapons, use this :) . This mod will automatically activate both of my previous mods, "Calamity Trigger Neo" and "Desperado" even in Singleplayer mode, Campaign, Realism etc. As this is a vscript mod with "scripted mode", it will probably have conflicts with other custom weapon mods using "scripted mode", but it works well with other mutation mods & any weapon skin mods with modified scripts inside. & this is recognized by the system as the part of the system, so the achievements are not disabled when using this.
In short, this mod includes the previous custom melee weapons with the powers to burn zombies and heal the wielders, and the "desperado" guns that have various effects depending on what guns you're using, like, healing ability, health buffer ability, auto incendiary ammo, auto explosive ammo, auto laser sight, and auto explosion (like the propane tank/ grenade launcher).
Well, enjoy the mod...
Note: If you, by chance, still don't know which slot the melee weapon is in this mod, try to press 7. I put it on slot 7 to make it able to carry both pistol and melee weapon.
*Updated: Added "Petrol Bullet" :D .
*Updated: Added a new "bug" on purpose :D .
*Updated: Added kind of a little help if you, by chance, are playing on a custom map with low to no melee weapon. The clue is: look for oxygen tank, & your wish is granted :D .
*Updated: Added some major changes on the effects of the guns.
* Updated: Added a function "Update" about healthbuffer boost per second without pills & adrenaline shot, abilities to rise from incapacitation, rise from hanging on the ledge without help, & escape from special infected when caught. Every 30 second, bots straying from the team will be warped behind the players. See the Changelog for details.
