Hey guys,
These are my class zero human ship types that I use to replace the stock designs at the beginning of the game. Their stats should tell you what they're built for, and you should be able to see where they outclass their stock counterparts. The Lance design is a basic light fighter hull template for use as the early weapons come up. It's meant primarily for early starbase and planetary defense.
