What is the outcome of the fight scene at the end?Act 5

The outcome of the fight that pretty much ends the play is that everyone dies.  Or at least Hamlet, Laertes, Gertrude, and Claudius all end up dead.

Gertrude is the first to die.  She drinks from the cup of wine that Claudius has poisoned.  It was meant for Hamlet, but Gertrude drinks from it first.

Then Claudius dies next.  Laertes tells Hamlet that Laertes' sword was poisoned and that Claudius was responsible.  Hamlet stabs Claudius with the sword and makes him drink the rest of the poisoned wine.

Laertes and Hamlet then die from the poison that was on Laertes' sword.
