This addon only works in Left 4 Dead 2.
A small proximity sensor is added to all deployed ammo upgrades. After the 5 second safety timer runs out, the sensor becomes active and any living thing walking there will cause all the deployed ammo packs explode. This also means that if the players utilize the ammo upgrades, the power of the mine is reduced since there is less ammo on the ground to explode.
Installation
As usual. Make sure you also have [url=http://addons.eventscripts.com/addons/view/srcds/]SRCDS Tools[/url] installed.
