I finally joined the SF club! The emblem stays on forever now.

Far too many attempts but I got it.

Solar Warlock w Sunbracers ALH+CC Riptide, S4A+Incandescent Epochal Integration, Xenophage for everything till the final boss. Then I swapped Xenophage for Recon+B&S Apex Predator, and brought Sunshot.

On to the next one!
