Mercenaries! We need your help! Gray Mann has once again decided to step into our parade and he's trying to mess up one of our agricultural facilies! Gear up and defend our honor!
And if you thought that defending your base from a massive onslaught of robots was hard, try defending your base from a massive onslaught of robots while Mother Nature herself is shoving a boot up your arse!
That's right! The forecast predicts hurricane-grade winds, a massive THUNDERSTORM, and a mean robotic invasion.

But that's not all! The area features THREE different avenues of attack that the robots can choose. And none of their paths are the same. They could be firing at you from the above, or they could be squeezing in through the narrow corridors. They're coming from everywhere, so that's why we're gonna need you to be MORE EVERYWHERE!
Get your rain boots* and prepare to be soaked!

After years of sending the same robots over and over, Gray Mann seems to have rethought his strategies. He's now inventing new weapons and adding THREE new elite giants into his robot hordes! Unfortunately, you won't be getting your hands on those weapons any time soon. Though you can be shot by them as these pictures we just recovered illustrate:
