Everyone please make a stealth and a perception roll.<br/><br/>Is the team looking for an airlock or going for one of the holes in the ship?<br/><br/>A few notes, we'll assume they can be gained with a take 10 on engineering or are just common knowledge:<br/><br/>The ship's outer hull is probably armoured and potentially double-layered.  They could cut through it but it would take a very long time to do so, probably measured in hours even for a small hole.<br/><br/>The ship would have a large number of internal pressure doors/seals.  It is likely, given the state of the ship and under the assumption that people are living there, that some parts are pressurized and others are not.  The majority of said seals would not be easily opened once inside as they are designed to prevent the catastrophic, explosive, death of the crew.  In general movement around (once partial pressure was lost) would be through external (or potentially internal) airlocks.  As a result the ship probably has a large number of airlocks at intervals along the hull.  The downside is that it is a military ship and they aren't necessarily intended to be opened (easily at least) from outside, and that is assuming the mechanism still works.  The ship is old and damaged, there is clearly some power due to the lights, but even if the central computer is still running it is unlikely that the ship is fully networked any longer.<br/><br/>Reva figures that the best bet is an airlock that is powered but no longer connected to the central computer.  It would be more easily hacked, but still have power to open.  Failing that, if they want to cut through, an unpowered airlock would be quicker than the hull and likely wouldn't set off any alarms.<br/><br/>There are probably local and global pressure alarms.  The local alarms would go off if they detect a drop in pressure in their vicinity.  The global would only go off if the local one that detects the drop is still connected to the central computer.<br/><br/>I probably should have posted this sooner:<br/>(https://i.imgur.com/lzEUUs6.jpg)<br/><br/>The front of the ship is buried in the ridge.  The bottom hangar is partially exposed.  The windows that are visible in the image are covered in blast doors, so the team doesn't see any that stand out from the rest of the hull.  They might be slightly easier to cut through than the hull itself though.  The top bridge is completely gone, that is where the crater is, however there is likely a second redundant combat bridge elsewhere on the ship.
