They partially seem like the answer to early WZ FF air waves. As long as you hide quickly when they start aggroing you, I was able to clear out all the normal Banshees on a wave and 1 out of the 4 hero Banshees without trouble (and then I melted under three seconds of sustained fire.)

Definitely a game to use your REQs, and while vehicles can get you through a lot of it (Wraith Ultra is basically all you need) the interior bosses do demand heavy explosives.

It's kind of easy to lose early without a communicative and/or competent team because until you get those REQs it's all about coordinating fire.

Having a blast with it.
