<Snipped quote by Heroic>
*the normal doors open*
Orion: perfect. This will allow for equal observation while keeping them sealed.
Shinji: in each room there is a vacuum sealed door to space, and beside it a breathe-kit for temporary exposure. Put it on. Once your ready, open the door and let an energy blast out. Trap or not, they'll come. They think either way that they will succeed, and that's what we're counting on.
Is it necessary if the void of space is not a big deal to me?
