Halo: Escape the Mothership

You take the Needle, and you run out the door, only to find yourself inside a room with four Elites and a Skirmisher.

Elite 1: Hey, that Spartan escaped! Teach him a lesson!
Skirmisher: Yeah, but not only that, we should-

You shot the Skirmisher in the face and he dies.

Elite 2: No, let's not teach him a lesson, let's settle for getting a promotion!
Elite 4: I agree!
Elite 3: Me three!
Elite 1: Okay, I go for that!

All four Elites run at you, energy swords drawn. You shoot one, and he staggers backward before running again. You shoot another three times with your Spiker. He brushes it off as if the were dust balls shot at him. You can't win. You run back into other room, and shut the door just as one of the Elites ran up to you. That Elite gets knocked right out.
