Boss Spawn Time
This page simply condenses all of the boss spawn intervals into one place for convenience.
Boss Spawn Intervals:
Every 28.5 minutes:
the Alien Punisher will spawn.
Every 60 minutes:
the Pirate Freighter X-0 has a random chance to spawn.
(another Punisher will also spawn near this time)
Every 70 minutes:
The Pirate Galleon will spawn.
Every 120 minutes:
The Alien Decimator will spawn.
(Punisher will spawn 5 minutes before this and at the same time X-0 can possibly spawn.)
Every 240 minutes:
The Pirate Super Capital Ship Kodiak will spawn.
(at the same time a Decimator, and possibly X-0 will spawn)
