I know what Secret Plasmid #2 is:

Level 1: Summons Jack from Bioshock 1 and he pwns all the splicers like the good old days.

Level 2: Summons Delta (from beyond the grave) from Bioshock 2 and he pwns even harder than Jack.

Level 3: Summons both of them. Delta and Jack team up and offer pwnage of epic proportions. And when the fight is done, they sing you a song.
