Archotech centipede death robot

From Acrab news, the in universe press:
"Mixed news. About 180 days ago, three unicorns went missing. However, they were finaly found by soldier search team. On a completly different continent's coast, on Melosator. While relieved that the military was there. They informed the search team that backup is needed. Because their grant project, which was almost finished, has provoked pirates. Who were going to attack them for it.

 
After some time, officers decided to deploy soldiers. Being told, the project in question was a living weapon. The deployed soldier managed to defeat the pirates, taking heavy losses. Leaving pretty much just the original three unicorns left, with their project completed. 
 
A giant centipede like robot emerged from an artificial womb, awaiting orders.
 
Unable to do anything to stop the unicorn nicknamed Sheet. The soldiers with the other two unicorns have returned back home, on a motor boat. Leaving Sheet to rampage madly through pirates and tribals alike, while mounted on the archotech centipede."
