What is Red Barrel?
1.
Gaming term.
A red barrel is any object that will explode violently when shot, damaging all surrounding objects/enemies.
Almost all shooters have red barrel.
It does not have to be red, nor does it have to be a barrel.
First appeared in the FPS Doom, wherein barrels of toxic waste would explode when shot, turning nearby enemies into piles of red slush.
If you shoot that red barrel, you can take them all out.
Damn! I just got killed by my own red barrel!
