The Stealth cruisers are best for unlocking the Mantis cruisers as they start with Long Range Scanners , which makes it easier to find the specific event required to unlock the ship . You will need be following systems installed in order to successfully unlock the Mantis CruiserLevel 3 Sensors OR Level 1 TeleporterLevel 2 MedbayClonebayEDIT Other good ships to unlock this event might be either Slug A has an AntiBio Beam , but you ' ll need to buy sensors before you visit the Homeworlds , Rock B starts with a Fire Bomb , and Mantises are shit at putting fires out , Lanius BCrystal BFederation C all of them start with a TeleporterYou also need to kill the crew of Kazaak ' s ship to get the event . Worse case , you can always shoot the O 2 and wait for them to choke .
