We grab the metal poles from the nearest selenites and swing them wildly!
With our superior Earth muscles we knock down ten selenites at a time! We almost reach the big doors, but they've been barred and locked! There's another exit at the opposite end of the hall, but can we make it without being caught? They're assembling some kind of big gun - could we get it and use it against them? I think we have zero chance of success!
Should we run back to the other exit? Or should we take the suicide mission - try to run for the gun and grab it before they can fire it? I mean, we're going to die anyway, right? Or do something else?
