MCST Heavy Class - Official Starblast Wiki

These ships are typically very tough, heavy and powerful, however are easy targets to hit due to their large size and very low mobility. Many have a round shape, and typically weapons are powerful and slow-firing, though this is not always the case. A good choice for players who wish to be able to take and deal heavy hits, without having to worry about dodging.
