I just want all the ships! Got the Mantis Cruiser two days ago. All that is left (of type A layouts) is the Crystal Cruiser. But it is so random to get it!
Randomly find a stasis pod in a decaying crystal ship (and the ship might shoot a shard at you making you automatically pull back!)
Randomly find a Zoltan research station (and there might be a battle to take it!)
Hope to all the gods in the universe that you can still reach the Rock home worlds (I got the crystal guy once at sector 7. Yeah.)
On a side note, put some frigging guns on the Fregitae! It looks way cool but is near impossible to use.
