This thing is basically your "oh ♥♥♥♥" button when everything goes sideways. Got enemies closing in from all directions? Time to make it rain.
It's a bunch of rocket launchers all pointed straight up that fire at once. The rockets go up, then come crashing down all around you in a circle of explosions. Super effective for when you're surrounded and need to clear some breathing room.
Fair warning though - this will mess up everything in the area, including you if you're not careful. The blast radius is pretty huge so make sure you've got some cover or distance before you hit the button.
Perfect for those moments when stealth goes out the window and you just need to turn the whole area into a crater. Not exactly subtle, but it gets the job done when you're backed into a corner.
Works great against groups of enemies or when you need to buy time to get out of a bad situation. Just don't use it if you've got friendlies nearby - trust me on that one.
