A plugin that makes Demoman's first primary weapon even stronger. I made it for my server but I figured I'd share it here too.
With this, pipes "think" every time they collide with something. If they can damage someone (including yourself) within its radius, it detonates.
It's not perfect as it has to wait a frame to detonate, but it gets the job done. I think it'd be pretty fun on jump servers too.
