Well... to put it frankly, the kinds of things you'd need that suit for. I said we had contact, I didn't say that we enjoyed it. With the exception of one species, they've all wanted to either invite us into their life cycles as food or a host, or invade and subjugate us. Neither one we were really prepared for.

When an accident [well... to HIM it was an accident.] tore holes in the brane demarcation between worlds and left them to freely enter, we lost most of the science team.
