Wave 33

Comments
In this and subsequent waves the ships that will spawn are all the same color as the bosses, Also they seem to spawn the same designs as Tier 4 waves, but in a random way so you can have 8 different designs against you.

Also as the bosses being the same color as the ships in these waves, they will join the spawned ship to fight you.

it's pretty easy to get outnumbered when multiple Xiphosuras start to appear and ally with the wave's ships.
