You did ask for this to be delivered here didn't you?
The Mail Strike is a wind driven air-delivered monstrosity consisting of only the finest parcels.
This weapon really is 'first class'.
Each letter can deliver up to 50 points of damage.
See that enemy Worm dug in? Thinking he can't be damaged, well he better think again because once these deliveries of doom are deployed he better get digging some more!
