How do you free princess lilandra from the shir ship?

The easiest way to save her is to use some one with slow time power. Use slow time or what ever it is called ( spider sense, stop time ) run straight for the tower you need to destroy, leave the bad guy alone for now. When you get to the room with Lilandra in it destroy the tower then go to the consel to the right of her. Destroy it, it is not that hard on easy or normal, but hard is dificult. As long as you keep your team together and tell them to attack the consel with you your good. You get more time added to the count down with every tower you destroy so don't miss any before you get here, there should only bee one more in the next room.

destroy the console to the right of her.

You have to destroy the machine or machines that are trapping her

By destroying the machines or machine that is torturing her

my team keeps going after the dam enemies were skipping and wont help me destroy the controls and even when using one of the rapid fire powers the dam things health goes down so slow what is going on with this

You must destroy the towers that are keeping her hostage. Use someone who can slow time like Silver Surfer,Spider Man, Thor, or whoever else.

After destroying the pilars, destroy the console next to lilandra, as said before it's easier if you have someone that can stop time.
