I haven't seen anyone mention yet even though someone probably has, but to be on the safe side I noticed the Ruiner has an auto attack icon and even exhibits attack behavior by approaching enemy targets, but is unable to fire at any time. It supposedly has a pulse gun, but cannot use it for whatever reason. There are two small holes on the front of the ship that could be used as the gun ports so I imagine it's just an error that IC hasn't been able to get to yet.
