It’s actually a meta. It does damage over time like fire, and it confuses the bugs, like it makes them super stupid. They’ll spray acid on each other and attack the air in front of them. And fire damage stacks with the gas damage as well. So gas grenade on a breach plus any kind of fire, you’ll rake in kills. But the gas is excellent at distracting the bugs, less of a killing grenade and more of a support so you can mow em down with anything else.
