it's very much open to interpretation but I guess you could think of a Last Stand as a 'final resistance' or a 'final battle' - it's the penultimate 'thing' that happens before a situation is resolved. So the CLASSIC example that I think we'll see a lot of in this game jam, is for example, a Tower Defense style game where the brave lone soldier has to survive an onslaught of enemies in their 'last stand. I hope that helps to explain it a bit more.
