This is another plugin created for me by Atomic Stryker. I am here just to share it. This plugin is best used in TAAANNK Gamemode (mutation19).
The only event that could not be unlocked is the 2nd door inside the RV on c5m2_park.
Atomic stryker described it to me like this.
To install place finale_unlocker.txt into addons/sourcemod/gamedata and finale_unlocker.smx into your addons/sourcemod/plugins folder.
This plugin requires stripper source for some maps and the plugin for others.
Place the stripper map configs into addons/stripper/maps.
