A tower of dispenser guns which will (eventually) go from bedrock to sky limit. Each dispenser floor has a "pulsar core" which, when connected to the outer rings, fires all dispensers rapidly. 8 arrows per second per dispenser, so when all are firing it'll belt out 160 arrows per second (in different directions of course) per floor.

Will update the schematic as i build it higher. Currently it has 4 dispenser levels, so it'll fire 640 arrows per second if all are activated. Each dispenser can fire for 2 whole minutes with 9 stacks of arrows. The schematic contains enough redstone floating around to activate all the floors, simply connect the pulsating core to the outer rings, climb a ladder, and repeat.

I would greatly appreciate it if you used this link to download the file, just click "skip ad" in the upper right corner of the site to reach the mediafire download page: LINK

Additional Notes

Causes a bit of lag when fully activated... not too bad though
