Noisy Cricket, thats prolly one of my favorite weapons too.

As for the acid rain idfea, I was thinking a dropship modeled to look like a cloud, and instead of the thrusters firing shortrange bullet particles, apply thrust to them would instead generate green gravity affected particles with fairly high penetration. It's a cloud you can fly that kills things and rapes the terrain when you move it basically. Or even when you dont move it.

*update*

Thorium fission bomb added.

A large glass contraption which you throw, and after 30 seconds it explodes in a massive firey explosion with lots of fire, and also spreads radiation all over the place. (I really like how I did it)
If you kill it before then, it spreads a small amount of radiation and doesn't explode. (thorium is radioactive)

Thorium is from Mass Effect.

Hah, thorium does exist in the real world if you've ever studied the periodic table.
