She would know it is vulnerable to 'traumatic' damage (critical hits) and electricity.  It probably has some form of Darkvision, and as such is unlikely to be able to tell a hologram from a person.  It likely has some method of healing itself at least once.  It is immune to bleed, death, disease, mind-affecting, necromancy, paralysis, poison, sleep, stun and anything that requires a fort save (that doesn't specifically target constructs).<br/><br/>Otherwise it probably doesn't have any powers beyond its weaponry.<br/><br/>The only paths that the group know about is into the hallway, or back out the airlock.  You haven't found any other exits from the little side area you are in (though can make a perception roll if you want to take some time to search around).  Off the hallway there are plenty of exits, but from where you are all but one (the one without a forcefield) you can't easily tell them apart.  The lack of a force field on the one does imply that it pressured like the main hallway however.<br/><br/><div class="quoteheader"><div class="topslice_quote"><a href="https://elliquiy.com/forums/index.php?topic=315315.msg15296980#msg15296980">Quote from: PerpetuallyAnnoyedCleric on 01-03-2020, 07:12:32</a></div></div><blockquote class="bbc_standard_quote">A peak aft, at least as far as she could see without opening the hatch further, revealed a number of corridors branching off the main hallway.  One of them, maybe thirty feet aft, lacked the telltale shimmer of the force-field.<br/></blockquote><div class="quotefooter"><div class="botslice_quote"></div></div>
